本发明涉及网络搜索技术领域，尤其涉及一种对查询序列进行扩展处理的技术。The invention relates to the technical field of network search, in particular to a technology for expanding and processing query sequences.
背景技术Background technique
随着网络搜索技术的不断发展，用户在进行网络搜索时，对快速获得全面准确的搜索结果的要求也越来越高。现有的网络搜索技术，为了尽可能的向用户提供全面的搜索结果，通常直接对用户的查询序列进行扩展处理，不考虑该查询序列是否需要进行扩展，并根据仅基于扩展后的查询序列向用户提供相应的扩展搜索结果。With the continuous development of network search technology, users have higher and higher requirements for quickly obtaining comprehensive and accurate search results when conducting network search. In order to provide users with comprehensive search results as much as possible, the existing network search technology usually directly expands the user's query sequence, regardless of whether the query sequence needs to be extended, and based only on the extended query sequence to The user provides corresponding extended search results.
然而，上述做法直接导致的问题是，由于对不需要进行扩展处理的查询序列也进行了扩展，使得基于原查询序列获得的搜索结果被基于扩展后的查询序列获得的大量扩展搜索结果所淹没，用户无法在短时间之内准确地获取其希望得到的目标搜索结果，提高了用户的搜索成本以及网络搜索设备，如搜索引擎服务器等的工作运行成本，并且降低了用户搜索效率及用户搜索体验。However, the problem directly caused by the above approach is that the search results obtained based on the original query sequence are overwhelmed by a large number of extended search results obtained based on the extended query sequence due to the expansion of the query sequence that does not need to be expanded. Users cannot accurately obtain the target search results they want in a short period of time, which increases the user's search cost and the operating cost of network search equipment, such as search engine servers, and reduces the user's search efficiency and user experience.
因此，如何提供一种对查询序列进行扩展处理的方法或设备，实现有条件地对查询序列进行扩展处理，成为目前亟待解决的问题之一。Therefore, how to provide a method or device for extending the query sequence, so as to conditionally extend the query sequence, has become one of the problems to be solved urgently.

When the historical transformation frequency exceeds the transformation frequency threshold, it is judged that the query sequence is satisfied. extended trigger conditions. For example, assuming that the conversion frequency threshold of the query sequence within 20 minutes is 80, according to the user query history records, the extended processing device 1 detects the statistical historical conversion frequency of a large number of users of the query sequence "apple" in the previous 20 minutes, if the statistical historical conversion frequency If it exceeds 80, it is determined that the extended trigger condition for performing extended processing on the query sequence is satisfied.

The number of corresponding search results, or the number of search results returned by the detection search engine based on the query sequence, when the number is lower than the threshold of the number of search results, it is determined that the expansion trigger condition for expanding the query sequence is met. For example, assuming that the query sequence is “Looking for rent-seekers in Shenyang Rent a House Net Railway West District”, the search engine performs a matching query on the query sequence in the search index database, and the number of corresponding search results obtained is 2. If the number of preset search results If the number threshold is 8, then the extension processing device 1 detects and determines that the extension trigger condition for performing extension processing on the query sequence is satisfied.

Here, the historical viewing volume of the search results corresponding to the query sequence includes the number of search results browsed by the user in the search results corresponding to the query sequence; The search results obtained by the search fail to meet the user's search needs. For example, assuming that the query sequence is "sea", according to the user query history records of the current user, the expansion processing device 1 obtains 1 historical page views of the search results corresponding to the query sequence, and the corresponding page view threshold is 2, then determine An extended trigger condition for extended processing of the query sequence is satisfied.

Here, the matching degree of the search result corresponding to the query sequence and the query sequence is determined based on the matching mode of the search result and the query sequence, wherein the matching mode includes exact matching and fuzzy matching, and the exact matching includes query sequence and search result in the search index The corresponding query keywords in the library are exactly the same, fuzzy matching includes that the query sequence and the search results in the search index library correspond to the same query keywords, and the matching degree of the exact match between the search result and the query sequence is greater than that between the search result and the query sequence Matching degree of fuzzy matching. For example, assuming that the query sequence is "Looking for rent-seekers in Tiexi District of Shenyang Rental Housing Network", the query sequence is word-segmented to obtain the corresponding keywords "Shenyang", "rental", "Tiexi District" and "rent-seeking" , and the search engine obtains the corresponding search results based on only some of the keywords according to the fuzzy matching mode. At this time, the matching degree of the search result and the query sequence is 2, and the corresponding matching degree threshold is 3. Then the extended processing device 1 judges whether The extended trigger condition for extended processing of the query sequence.
