背景技术Background technique
POI(Point of Interest，兴趣点)是指用户感兴趣或对用户来说有实际用途的特定的地理位置点。在地理信息系统中，一个POI可以是一个商铺、一个公交站，一个学校等，拥有大量丰富且准确的POI通常被认为是电子地图产品的核心竞争力。POI (Point of Interest, point of interest) refers to a specific geographical point that is of interest to the user or has practical uses for the user. In a geographic information system, a POI can be a store, a bus stop, a school, etc. Having a large number of rich and accurate POIs is generally considered the core competitiveness of electronic map products.
目前，电子地图的POI主要由地图提供商定期提供，地图提供商人工收集海量POI后将收集的POI标注在电子地图上。而实际上，每天都会有大量的POI新点产生，按照地图提供商提供POI的速度很难满足地图产品的需求，POI新点的挖掘及时性差。At present, POIs of electronic maps are mainly provided regularly by map providers, who manually collect a large number of POIs and mark the collected POIs on the electronic map. In fact, a large number of new POI points are generated every day. According to the speed of POI provided by map providers, it is difficult to meet the needs of map products, and the timeliness of mining new POI points is poor.

具体实施方式Detailed ways
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
图1示出了根据本发明一个实施例的挖掘地图兴趣点POI的方法的流程示意图，参见图1，本实施例的挖掘地图兴趣点POI的方法包括下列步骤：Fig. 1 shows a schematic flow chart of a method for mining map POIs according to an embodiment of the present invention. Referring to Fig. 1, the method for mining map POIs of this embodiment includes the following steps:
步骤S101，获取预设时间段内产生的地图垂直搜索日志，组成第一搜索日志集合；Step S101, obtaining map vertical search logs generated within a preset time period to form a first search log set;
这里的预设时间段，比如每月。即，本步骤中按月为周期获取一个月内产生的地图垂直搜索日志，将这些地图垂直搜索日志组成第一搜索日志集合。基于第一搜索日志集合以得到新的POI。从而与现有技术中主要靠地图提供商提供POI数据且数据提供周期以季度为单位相比，能够根据地图使用中产生的日志数据及时、有效的挖掘新的POI，实现了基于用户反馈(即用户的地图搜索日志)来及时扩充高质量POI新点的效果，拓展了POI新点挖掘新路径。The preset time period here, such as monthly. That is, in this step, map vertical search logs generated within one month are acquired on a monthly basis, and these map vertical search logs are combined into a first search log set. A new POI is obtained based on the first search log set. Therefore, compared with the prior art that mainly relies on the map provider to provide POI data and the data providing cycle is quarterly, new POIs can be mined in a timely and effective manner according to the log data generated in the use of the map, and realized based on user feedback (i.e. The user's map search log) to timely expand the effect of high-quality POI new points, and expand the new path of POI new points mining.
步骤S102，对第一搜索日志集合进行过滤处理，得到第二搜索日志集合；Step S102, performing filtering processing on the first search log set to obtain a second search log set;
步骤S103，对第二搜索日志集合中的各搜索日志中的查询词进行完善处理，得到新的POI。In step S103, the query words in each search log in the second search log set are perfected to obtain a new POI.
由图1所示可知，本实施例的挖掘地图兴趣点的方法，通过获取预设时间段内产生的地图垂直搜索日志，进行过滤处理，基于过滤后得到的第二搜索日志集合对搜索日志中的查询词进行完善处理得到新的POI。从而可以基于海量的用户使用日志数据，主动、及时的挖掘出新的POI，提高了POI的挖掘速度，并且经过过滤处理过滤掉低质量的日志也保证了挖掘出的新的POI的准确性。As shown in FIG. 1, it can be seen that the method for mining map interest points in this embodiment, by obtaining the map vertical search log generated within a preset time period, performs filtering processing, based on the second search log set obtained after filtering, sorts the search log The query words are perfected to get a new POI. In this way, new POIs can be actively and timely mined based on massive user log data, which improves the POI mining speed, and filtering out low-quality logs through filtering also ensures the accuracy of the mined new POIs.
在本发明的一个实施例中，前述步骤S102中对第一搜索日志集合进行过滤处理，得到第二搜索日志集合包括：对第一搜索日志集合中的每条搜索日志，判断该搜索日志中的查询词是否有地图需求，如果有地图需求则将该搜索日志放入第二搜索日志集合中，如果没有地图需求则过滤掉该搜索日志。In an embodiment of the present invention, in the aforementioned step S102, filtering the first search log set to obtain the second search log set includes: for each search log in the first search log set, judging the Whether the query word has a map requirement, if there is a map requirement, put the search log into the second search log collection, and if there is no map requirement, filter out the search log.
这里的有地图需求是指用户的搜索查询需求是指向搜索地图的，而非指向地图之外。考虑到现有的地图产品的功能十分丰富，可以满足用户的多种搜索查询需求，比如，对快递的查询需求，对路线的查询需求，对拥堵状况的查询需求等。这些查询需求对于挖掘POI新点来说，可以被认为是干扰数据，因此，本实施例中通过地图需求这一过滤条件，将那些没有地图需求的搜索查询日志过滤掉，从而减少了数据处理量，并保证了挖掘的POI新点的质量。The need for a map here means that the user's search query needs point to the search map, rather than pointing to the outside of the map. Considering that the existing map products are very rich in functions, they can meet various search and query needs of users, such as the query needs of express delivery, route query, and congestion status query. These query requirements can be considered as interference data for mining new POI points. Therefore, in this embodiment, through the filter condition of map requirements, those search query logs without map requirements are filtered out, thereby reducing the amount of data processing. , and guarantee the quality of new POI points excavated.
而判断一条搜索日志中的查询词是否有地图需求的一个具体实施方式是通过调用预设的地图需求打分接口来获取该搜索日志中的查询词的得分；根据该搜索日志中的查询词的得分确定是否有地图需求。And a specific implementation manner of judging whether a query word in a search log has a map requirement is to obtain the score of the query word in the search log by calling a preset map requirement scoring interface; according to the score of the query word in the search log Determine if there is a map requirement.
也就是说，本发明一个实施例中，通过一个打分机制判断当前搜索日志中的查询词是否有地图需求。举例而言，如果调用预设的地图需求打分接口来获取的当前搜索日志中的查询词的得分为“score:288”，即地图需求打分接口返回有效得分，说明当前搜索日志有地图需求。如果地图需求打分接口返回“无有效得分”，说明当前搜索日志没有地图需求，这些搜索日志将会被过滤掉而不会进入到后续的流程中。That is to say, in one embodiment of the present invention, a scoring mechanism is used to determine whether the query words in the current search log have map requirements. For example, if the score of the query word in the current search log obtained by calling the preset map requirement scoring interface is "score: 288", that is, the map requirement scoring interface returns a valid score, indicating that the current search log has a map requirement. If the map request scoring interface returns "No valid score", it means that the current search log has no map request, and these search logs will be filtered out and will not enter the subsequent process.
在本发明的一个实施例中，前述步骤S102中对第一搜索日志集合进行过滤处理，得到第二搜索日志集合包括：预设一个或多个查询词排除类型，对第一搜索日志集合中的每条搜索日志，判断该搜索日志中的查询词是否属于查询词排除类型，如果属于则过滤掉该搜索日志，如果不属于则将该搜索日志放入第二搜索日志集合中。In one embodiment of the present invention, in the aforementioned step S102, filtering the first search log set to obtain the second search log set includes: preset one or more query term exclusion types, and filter the first search log set For each search log, it is judged whether the query word in the search log belongs to the query word exclusion type, if it is, the search log is filtered out, and if it is not, the search log is put into the second search log set.
这里的查询词排除类型是指在挖掘POI新点过程中不感兴趣的查询词类型，例如，公交线路类型(如402路)，地铁线路类型(如地铁10号线)和路线类型(如A地点到B地点)。这些查询词通常也不是待挖掘的POI新点对应的查询词，所以，本实施例预设一个或多个查询词排除类型，然后将第一搜索日志集合中的每搜索日志的查询词和预设的一个或者多个查询词排除类型进行一一比较，判断搜索日志的查询词是否属于查询词排除类型，如果属于查询词排除类型就把这条搜索日志过滤掉，如果不属于查询词排除类型，那么把该搜索日志放入第二搜索日志集合中。第二搜索日志集合中的搜索日志是可靠性和准确性比较高的那些搜索日志，可能被用来生成新的POI。The query word exclusion type here refers to the type of query words that are not interested in the process of mining new POI points, for example, bus line type (such as 402 road), subway line type (such as subway line 10) and route type (such as A location to location B). These query words are usually not the query words corresponding to the new POI points to be mined. Therefore, this embodiment presets one or more query word exclusion types, and then combines the query words of each search log in the first search log set with the predicted query words. One or more query word exclusion types are compared one by one to determine whether the query words in the search log belong to the query word exclusion type. If they belong to the query word exclusion type, filter out this search log. If they do not belong to the query word exclusion type , then put the search log into the second search log set. The search logs in the second search log set are those with relatively high reliability and accuracy, and may be used to generate new POIs.
在本发明的一个实施例中，如果要挖掘新的POI点，就需要将搜索日志中的查询词与线上已经存在的POI对应的查询词相同的搜索日志过滤掉，从而只留下那些与线上已经存在的POI对应的查询词不同的，可能挖掘出新的POI的搜索日志。因而，前述步骤S102中对第一搜索日志集合进行过滤处理，得到第二搜索日志集合还包括：对第一搜索日志集合中的每条搜索日志，判断该搜索日志中的查询词是否为已知POI对应的查询词，如果是则过滤掉该搜索日志，如果不是则将该搜索日志放入第二搜索日志集合中。In one embodiment of the present invention, if new POI points are to be excavated, it is necessary to filter out the search logs whose query words in the search log are the same as the query words corresponding to POIs already existing on the line, thereby only leaving those If the query words corresponding to POIs that already exist online are different, it is possible to dig out the search logs of new POIs. Therefore, in the aforementioned step S102, filtering the first search log set to obtain the second search log set further includes: for each search log in the first search log set, judging whether the query words in the search log are known If the query word corresponding to the POI is, the search log is filtered out, and if not, the search log is put into the second search log set.
而判断该搜索日志中的查询词是否为已知POI对应的查询词的一个具体实施方式是，将该搜索日志中的查询词输入到POI数据检索引擎，根据POI数据检索引擎的返回结果判断该搜索日志中的查询词是否为已知POI对应的查询词；其中，POI数据检索引擎是根据线上已知的POI数据搭建的。And a specific embodiment of judging whether the query word in the search log is a query word corresponding to a known POI is to input the query word in the search log into the POI data retrieval engine, and judge the POI data according to the return result of the POI data retrieval engine. Whether the query term in the search log corresponds to a known POI; wherein, the POI data retrieval engine is built based on online known POI data.
也就是说，本实施例中利用一个根据线上已知POI数据搭建的数据检索引擎，将当前搜索日志中的查询词输入到POI数据检索引擎中，POI数据检索引擎检索后会返回结果，如果收到POI数据检索引擎返回的与已知POI对应的查询词相同的结果，则将此搜索日志过滤掉。否则，保留搜索日志。这样可以过滤掉线上已经存在的POI对应的查询词，留下的搜索日志中的查询词有很大概率就是新的POI对应的查询词。That is to say, in this embodiment, a data retrieval engine built based on known online POI data is used to input the query words in the current search log into the POI data retrieval engine, and the POI data retrieval engine will return the result after retrieval, if When the POI data retrieval engine returns a result identical to the query word corresponding to the known POI, the search log is filtered out. Otherwise, keep the search log. In this way, query words corresponding to POIs that already exist online can be filtered out, and the query words in the remaining search logs have a high probability of being query words corresponding to new POIs.
经过上面的过滤处理后，可以得到第二搜索日志集合，一个实施例中可以直接根据第二搜索日志集合中的搜索日志中的查询词生成新的POI。但是，考虑到第二搜索日志集合中的搜索日志数量仍然较大，为了进一步降低数据处理量，并提高新的POI的质量，本发明一个实施例中在得到第二搜索日志集合之后，并在对第二搜索日志集合中的各搜索日志中的查询词进行完善处理的步骤之前，进一步包括：对第二搜索日志集合中的各搜索日志的查询词进行优先级排序；则所述对第二搜索日志集合中的各搜索日志中的查询词进行完善处理包括：按照各查询词的优先级排序顺序对其进行完善处理。After the above filtering process, the second search log set can be obtained. In one embodiment, a new POI can be generated directly according to the query words in the search logs in the second search log set. However, considering that the number of search logs in the second search log set is still relatively large, in order to further reduce the amount of data processing and improve the quality of new POIs, in one embodiment of the present invention, after obtaining the second search log set, and Before the step of perfecting the query words in each search log in the second search log set, it further includes: prioritizing the query words in each search log in the second search log set; The perfecting processing of the query words in each search log in the search log set includes: performing perfect processing on the query words according to their priority order.
即，通过对第二搜索日志集合中的各搜索日志的查询词进行优先级排序，然后按照各查询词的优先级排序顺序对其进行完善处理。比如，第二搜索日志集合中的一条搜索日志中的查询词(奇虎360)的优先级为一级，而另一条搜索日志中的查询词(奇虎360附近的美食)的优先级为二级，那么，后续在完善POI新点对应的查询词时，先完善高优先级的查询词，即奇虎360这一查询词，在此之后，完善奇虎360附近的美食这一查询词。如此，能够将更加高质量的POI新点对应的查询词尽快完善出来，并得到挖掘的POI新点，提高了POI新点的挖掘速度和效率。That is, by prioritizing the query words of each search log in the second search log set, and then performing refinement processing on them according to the priority order of each query word. For example, the priority of the query word (Qihoo 360) in a search log in the second search log set is first level, and the priority of the query word (food near Qihoo 360) in the other search log is two Then, when improving the query words corresponding to the new POI points, first improve the high-priority query words, that is, the query words of Qihoo 360, and after that, improve the query words of food near Qihoo 360. In this way, the query words corresponding to the new POI points of higher quality can be improved as soon as possible, and the new POI points to be mined can be obtained, which improves the mining speed and efficiency of the new POI points.
本发明一个实施例中提供了对第二搜索日志集合中的各搜索日志的查询词进行优先级排序的实施方式，具体的，从第二搜索日志集合中的各搜索日志中分别提取字节数字段的值；字节数字段表示用户搜索时服务器返回的字节数；如果字节数字段的值小于第一字节数阈值，则为对应的搜索日志中的查询词分配高优先级；如果字节数字段的值大于第二字节数阈值，则为对应的搜索日志中的查询词分配低优先级；第二字节数阈值大于第一字节数阈值。An embodiment of the present invention provides an implementation manner of prioritizing the query words of each search log in the second search log set, specifically, extracting byte numbers from each search log in the second search log set The value of the field; the byte number field indicates the number of bytes returned by the server when the user searches; if the value of the byte number field is less than the first byte number threshold, the query word in the corresponding search log is assigned a high priority; if If the value of the byte number field is greater than the second byte number threshold, the query word in the corresponding search log is assigned a low priority; the second byte number threshold is greater than the first byte number threshold.
需要说明的是，第二搜索日志集合中的各搜索日志中均包含一个字节数字段，该字段记录了用户使用查询词在地图上搜索时，服务器返回的字节数。比如，用户使用查询词奇虎360附近的美食在在地图上搜索时，服务器返回的字节数为30(即，字节数字段的值为30)大于预设的第二字节数阈值12，那么即可为对应的搜索日志中的查询词(即，奇虎360附近的美食)分配低优先级。而如果用户使用查询词奇虎360在在地图上搜索时，服务器返回的字节数为8(即，字节数字段的值为8)小于第一字节数阈值10，则为对应的搜索日志中的查询词(即，奇虎360)分配高优先级。It should be noted that each search log in the second search log set includes a byte number field, which records the number of bytes returned by the server when the user uses the query word to search on the map. For example, when the user uses the query word Qihoo 360 to search for food near the map, the number of bytes returned by the server is 30 (that is, the value of the number of bytes field is 30) which is greater than the second preset threshold of 12 bytes. , then a low priority can be assigned to the query word in the corresponding search log (that is, food near Qihoo 360). And if the user uses the query word Qihoo 360 to search on the map, the number of bytes returned by the server is 8 (that is, the value of the number of bytes field is 8) is less than the first threshold of 10 bytes, then the corresponding search The query term (ie, Qihoo 360) in the log is assigned high priority.
之所以通过服务器返回的字节数的大小来为查询词分配不同的优先级是因为，当用户的查询词更趋近于一个POI新点时，服务器找到的POI结果数相应的很小，即满足查询条件的结果数量少，这也说明查询词很有可能是一个精准的POI。而如果用户的查询词更偏离POI新点，比如仅仅是一个返查询，那么服务器找到的POI结果数相应的就会很大，即满足查询条件的结果数量多。基于此，可以对第二搜索日志集合中的各搜索日志的查询词进行优先级排序。从而更及时、准确的发掘出POI新点对应的查询词。The reason why the query words are assigned different priorities by the size of the number of bytes returned by the server is that when the user's query words are closer to a POI new point, the number of POI results found by the server is correspondingly small, that is, The number of results that meet the query conditions is small, which also shows that the query word is likely to be an accurate POI. And if the user's query is more deviated from the new point of POI, for example, it is only a return query, then the number of POI results found by the server will be correspondingly large, that is, the number of results that meet the query conditions is large. Based on this, the query words in the search logs in the second search log set may be prioritized. In this way, query words corresponding to new POI points can be discovered more timely and accurately.
由上可知，本实施例的方法以地图垂直搜索日志为基础，利用查询词分析和数据检索引擎过滤等手段，高效的从预定时期内产生的(例如，每月)海量日志中挖掘出可能成为POI新点的查询词。As can be seen from the above, the method in this embodiment is based on the vertical map search log, and utilizes methods such as query word analysis and data retrieval engine filtering to efficiently dig out possible data from a large number of logs generated within a predetermined period (for example, every month). Query words for POI new points.
下面结合一个具体的示例对挖掘地图兴趣点POI的方法的步骤进行说明。The steps of the method for mining POIs on a map will be described below with a specific example.
步骤S201，获取日志数据。Step S201, acquiring log data.
本实施例中，以月为周期，获取线上地图垂直搜索日志，该地图垂直搜索日志记录有用户的查询词以及城市等信息。In this embodiment, the online map vertical search log is acquired on a monthly basis, and the map vertical search log records information such as the user's query words and cities.
步骤S202，筛选出有地图需求的查询词。Step S202, filter out query words that require maps.
每次处理时输入一条日志，通过一个打分机制判断当前搜索日志中的查询词是否有地图需求。Input a log for each processing, and use a scoring mechanism to judge whether the query words in the current search log have a map requirement.
例如，当前要处理的查询词为“中国乡镇企业协会”，调用预设的地图需求打分接口http://xx.qihoo.net/get_score？q＝中国乡镇企业协会获取该查询词的需求得分score。根据该搜索日志中的查询词的得分判断是否有地图需求。比如，得到的结果是“score:288”，即返回有效得分，则说明该搜索日志中的查询词有地图需求。相反，如果查询词为“快递查询”，调用预设的地图需求打分接口后返回“无有效得分”，说明无地图需求，这些搜索日志中的查询词就不会进入到后续的流程中。For example, if the current query word to be processed is "China Township Enterprise Association", call the preset map demand scoring interfacehttp://xx.qihoo.net/get_score? q = China Association of Township and Village Enterprises obtains the demand score of the query word. Whether there is a map demand is judged according to the score of the query word in the search log. For example, if the obtained result is "score: 288", that is, a valid score is returned, which means that the query term in the search log has a map requirement. On the contrary, if the query word is "express query", calling the preset map demand scoring interface returns "no valid score", indicating that there is no map demand, and the query words in these search logs will not enter the subsequent process.
步骤S203，过滤不感兴趣类型的查询词。Step S203, filtering query words of uninteresting types.
预设一个或多个查询词排除类型(即，不感兴趣的查询词类型)，利用查询词分析技术来分析步骤S202中通过打分的数据，将不感兴趣的类型的查询词过滤掉，如“公交”，“路线”等。One or more query word exclusion types (that is, uninteresting query word types) are preset, and the query word analysis technology is used to analyze the data scored in step S202, and the query words of the uninteresting type are filtered out, such as "bus ", "route", etc.
例如：当前要处理的查询词和城市信息的组合为“402路长沙”，判断该搜索日志中的查询词是否属于查询词排除类型，如果属于则过滤掉该搜索日志。具体的，本实施例中调用接口“http://xx.qihoo.net/qp？q＝402路&c＝长沙”，如果接口返回“bustype(bus)type:orig|402路公交线路{"queryinfo":{"route_info":{"tag":"","type":46,"trigger_type":0}}}”。则说明是一个“公交线路”类型的查询词，属于不感兴趣的查询词类型，则将该查询词所在的搜索日志过滤掉，即这类查询词也不会进入后续流程中。For example: the combination of the query word and city information to be processed is "402 Road Changsha", judge whether the query word in the search log belongs to the query word exclusion type, and if so, filter out the search log. Specifically, in this embodiment, the interface "http://xx.qihoo.net/qp?q=402 Road&c=Changsha" is called, if the interface returns "bustype(bus) type:orig|402 bus line {"queryinfo ":{"route_info":{"tag":"","type":46,"trigger_type":0}}}". Then it indicates that it is a query word of the type of "bus line", which belongs to the type of query word that is not of interest, and the search log where the query word is located is filtered out, that is, such query words will not enter the subsequent process.
步骤S204，过滤线上已经存在的POI对应的查询词。Step S204, filtering query words corresponding to POIs that already exist on the line.
本步骤中的处理是，将经过以上步骤的查询词输入到POI数据检索引擎中，该POI数据检索引擎是利用线上数据搭建的一个数据检索引擎，可以过滤掉线上已经存在的POI对应的查询词。留下的查询词被认为有很大概率是POI对应的查询词。The processing in this step is to input the query words through the above steps into the POI data retrieval engine. The POI data retrieval engine is a data retrieval engine built using online data, which can filter out the POIs that already exist online. query term. The remaining query words are considered to have a high probability of being the query words corresponding to the POI.
例如，调用下述接口，将查询词输入到POI数据检索引擎中。For example, call the following interface to input query words into the POI data retrieval engine.

根据POI数据检索引擎返回的结果分析线上是否已经存在该查询词对应的POI，若存在则将此查询词过滤掉。According to the results returned by the POI data retrieval engine, it is analyzed whether the POI corresponding to the query word already exists online, and if it exists, the query word is filtered out.
步骤S205，根据对应的查询词生成疑似新POI。Step S205, generating a suspected new POI according to the corresponding query words.
通过之前的几个步骤，得到的查询词已经初步可用，但搜索日志和查询词的数量依然较大。为提高使用效率，本步骤中进一步处理，即，对第二搜索日志集合中搜索日志中的的查询词分配优先级，优先完善高优先级的查询词。Through the previous steps, the obtained query words have been preliminarily available, but the number of search logs and query words is still relatively large. In order to improve the use efficiency, further processing is carried out in this step, that is, priority is assigned to the query words in the search logs in the second search log set, and high-priority query words are prioritized to be perfected.
需要说明的是，原始地图垂直搜索日志中有一个字节数字段标识了用户搜索时服务器返回的字节数，这个字段信息可以用来为查询词分配优先级。图2示出了根据本发明一个实施例的地图搜索结果示意图，图3示出了根据本发明一个实施例的另一地图搜索结果示意图。参见图2，当用户使用查询词“奇虎360”在地图上搜索时，服务器返回的字节数相对较少，只包含一个POI点(北京奇虎科技有限公司)的相关数据，说明服务器精准返回了某个POI。It should be noted that there is a byte number field in the original map vertical search log that identifies the number of bytes returned by the server when the user searches. This field information can be used to assign priority to query words. Fig. 2 shows a schematic diagram of a map search result according to an embodiment of the present invention, and Fig. 3 shows a schematic diagram of another map search result according to an embodiment of the present invention. Referring to Figure 2, when the user searches on the map using the query term "Qihoo 360", the server returns relatively few bytes, including only one POI point (Beijing Qihoo Technology Co., Ltd.), indicating that the server is accurate. A POI was returned.
参见图3，当用户使用查询词“奇虎360附近的美食”在地图上搜索时，服务器返回的字节数相对较多，包含了三个POI点(一个是360食堂，一个是怡乐餐厅，还有一个是赵生记汤包馆酒仙桥店)的相关数据。这就说明此查询词是一个泛查询，不是对某个特定POI的检索，对应的查询词优先级可以往后排。如此，通过设置字节数阈值，并将服务器返回结果的字节数和字节数阈值比较即可确定查询词的优先级。Referring to Figure 3, when the user searches on the map using the query term "food near Qihoo 360", the server returns a relatively large number of bytes, including three POI points (one is 360 canteen, the other is Yile restaurant) , and the other is the related data of Zhao Shengji Tang Bao Restaurant (Jiuxianqiao Store). This means that the query term is a general query, not a search for a specific POI, and the priority of the corresponding query term can be ranked at the back. In this way, by setting the byte count threshold and comparing the byte count of the result returned by the server with the byte count threshold, the priority of the query word can be determined.
步骤S206，完善查询词信息，得到新POI。Step S206, improving the query word information to obtain a new POI.
在本步骤中，对筛选出的第二搜索日志集合中的各搜索日志中的查询词进行完善处理，得到新的POI。具体的完善处理比如是通过一些爬虫手段从互联网页面中抓取与查询词相关的信息，比如地址信息，以完善查询词的信息，从而得到新POI。In this step, the query words in each search log in the selected second search log set are perfected to obtain a new POI. The specific improvement processing is, for example, grabbing information related to the query word from Internet pages by means of crawlers, such as address information, so as to improve the information of the query word, thereby obtaining a new POI.
后续，可以将经过上述步骤挖掘出的质量较高的新POI标注在电子地图上，实现扩充电子地图产品POI覆盖率，提高电子地图竞争力的目的。Subsequently, new POIs with high quality excavated through the above steps can be marked on the electronic map, so as to achieve the purpose of expanding the POI coverage of electronic map products and improving the competitiveness of electronic maps.
