Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

According to an aspect of an embodiment of the present invention, there is provided a method for retrieving information. In the present embodiment, the above-described information retrieval method can be applied to a hardware environment formed by the terminal 101 and the server 102 shown in fig. 1. As shown in fig. 1, a terminal 101 is connected to a server 102 via a network, including but not limited to: the terminal 101 may be a mobile phone terminal, or may also be a PC terminal, a notebook terminal, or a tablet terminal. The information retrieval method may be performed by a terminal or a server. The terminal can provide a retrieval interface of information so that the terminal or the server can obtain the keywords to be retrieved.

Fig. 2 is a flowchart of a retrieval method of information according to an embodiment of the present invention. As shown in fig. 2, the information retrieval method includes the following steps:

s202, obtaining target keywords to be retrieved.

The target keyword to be retrieved is a keyword of related content that the user desires to see, and information related to the user's desire can be retrieved through the target keyword. The target keyword may be a person name, a place name, an event name, etc., and may also be a term, a noun abbreviation, and a combination thereof.

S204, a first information set associated with the target keyword is retrieved from the first data cluster.

S206, retrieving a second information set associated with the target keyword from a second data cluster, wherein the data in the first data cluster comprises the data in the second data cluster, and the data in the second data cluster is current hot data.

The first data cluster and the second data cluster both contain information related to the target keyword. The first data cluster contains more information than the second data cluster. The first data cluster and the second data cluster may be a news cluster, a dictionary, a academic data cluster, a cluster of natural things, and the like. The first data cluster may be a full volume data and the second data cluster may be a partial volume data. The data in the second data cluster is part of the first data cluster.

For example, in a news cluster, a first data cluster may be a collection of all information in the network, and a second data cluster is a collection of more popular and focused information in the network.

For example, in a dictionary, the first data cluster may be a set of all information including a part of the dictionary, and the second data cluster is a set of information on chemistry or biology in a part of the dictionary, and may be a set of information on physics, a set of information on mathematics, or the like. Optionally, the second data cluster is a set of information related to the current technology hotspot in a dictionary. Such as vocabulary associated with blockchains, vocabulary associated with quantum communication, and the like. It should be noted that, as time goes by, the current technology hotspot changes, and then the data of the second data cluster also changes.

For example, in an academic material cluster, a first data cluster may be a collection of academic materials of all fields, and a second data cluster may be a collection of academic materials of a specific field. The domain-specific academic material may also be based on the current domain of interest. The second data cluster may also be a collection of academic material viewed a relatively large number of times.

The current hot data may be data with a relatively large number of views. For example, the first data cluster includes data in the second data cluster, and the number of times the data in the second data cluster is viewed is more than the number of times the data in the first data cluster is viewed.

And S208, generating a retrieval result in response to the target keyword, wherein the retrieval result comprises information in a first information set, the display position of a first part of information in the first information set in the retrieval result is earlier than the display position of a second part of information in the first information set in the retrieval result, the first part of information is information simultaneously contained in the first information set and the second information set, and the second part of information is information contained in the first information set but not contained in the second information set.

The search result is generated from the first data cluster and the second data cluster. Because the data in the second data cluster is the current hot data and the probability of being the search target of the user is higher, the information related to the target keyword is searched in the first data cluster and the second data cluster at the same time to obtain a first information set and a second information set, and the same data in the first information set and the second information set is preferentially displayed at the front end of the display position.

For example, the user searches two words of "Shenzhen", which serves as a target keyword to be searched. The information related to the Shenzhen searched in the first data cluster is shown in FIG. 3 (only partial information obtained by searching is shown in FIG. 3). The information presented includes information (1) Shenzhen strictly manages the takeaway guy violation … …; information (2) Shenzhen strictly manages takeaway serving trolley … …; information (3) Shenzhen … … in the warning and effective process of typhoon red police; information (4) Shenzhen academic tense condition aggravates … …. I.e. fig. 3 shows part of the information in the first set of information.

The information related to Shenzhen searched in the second data cluster, and the obtained second information set comprises information (1) typhoon "sky pigeon" attack! Collapse … … of the seawater pouring tower crane; information (2) Chen is Cheng as Gui elected Shenzhen. The retrieval result shown in fig. 4 is obtained according to the first information set and the second information set. The search result shown in fig. 4 further includes: information (3) Shenzhen strictly manages the takeaway Chige violation … …; and information (4) typhoon 'Tiange' positively influences Shenzhen and shutdown of the whole market. Here, the information (1), the information (2), and the information (4) shown in fig. 4 are also included in the first information set, but are not shown in fig. 3.

Wherein, the information (1) and the information (2) shown in fig. 4 are first part information in the first information set, the information (3) and the information (4) shown in fig. 4 are second part information in the first information set, and fig. 4 shows that the display position of the first part information is before the display position of the second part information. And preferentially displaying the information related to the target keyword in the second information set in the retrieval result. The typhoon related news is a content which is more concerned by the current user than the management of takeaway guy, so that the typhoon related news is displayed in the front of the display position and is more suitable for the search purpose of the user.

Optionally, before retrieving the second set of information associated with the target keyword in the second data cluster, the method further comprises: and capturing information of the target website according to the target time interval to obtain a second data cluster, wherein the target website is used for displaying current hot information.

The information in the second data cluster may be current trending information, e.g., current trending news for the first data cluster and the second data cluster being news clusters. The second data cluster may be obtained by crawling information in the network. Since the second data cluster includes current trending information that is updated in real-time, the second data cluster also needs to be updated in real-time. For example, updating the second data cluster at certain time intervals. The number of the information in the second data cluster is at least one, and the second data cluster is obtained by capturing the content of the target edition block of the target website.

For example, the news of the first key channel of the authoritative portal site is captured in real time to obtain the second data cluster. The first page news of the authoritative portal site is usually subjected to manual auditing operation, the importance and the news quality are both guaranteed, the news importance can be identified in an auxiliary mode through the characteristics of 'red', 'bold', 'rolling play' and the like on the page, and a second data cluster is obtained through identifying the news.

And the second data cluster is updated in real time to ensure that the information in the second data cluster is always hot information, and when the target keyword is received, the retrieval is directly performed in the second data cluster, so that the retrieval speed is improved.

In this embodiment, in addition to updating the second data cluster in real time, the method may further grab information related to the target keyword after receiving the target keyword to obtain the second data cluster, that is, optionally, before retrieving the second information set associated with the target keyword in the second data cluster, the method further includes: and after receiving the target keyword, capturing information associated with the target keyword at the target website to obtain a second data cluster, wherein the target website is used for displaying current hot information.

And capturing associated news in the target section of the target website according to the target keyword to obtain a second data cluster. In this case, the news included in the second data cluster is data related to the target keyword, and other data unrelated to the target keyword does not need to be captured, so that the data volume of the second data cluster is reduced, the transmission bandwidth occupied by transmitting the second data cluster can be reduced, and the storage space occupied by the second data cluster is reduced.

The information of the second data cluster can be obtained by screening from the first data cluster besides being directly captured from the target website. Optionally, before retrieving the second set of information associated with the target keyword in the second data cluster, the method further comprises: screening information with a source of a target website from the first data cluster; and taking the screened information with the source as the target website as a second data cluster.

Taking a news cluster as an example, the first data cluster comprises all news of the whole network, and information captured from a target edition block of a target website is screened out when the first data cluster is obtained, so that a second data cluster is obtained. That is, the second data cluster is obtained by screening the first data cluster according to the data source, and the second data cluster does not need to be captured again.

Optionally, after generating the search result in response to the target keyword, the method includes: sending a retrieval result to the client; or displaying the retrieval result.

The retrieval method can be executed by a terminal or a server, and when the retrieval method is executed by the server, the server sends a retrieval result to a client installed on the terminal so that the client can display the retrieval result; when the retrieval method is executed by a terminal (or a client installed on the terminal), the retrieval result is directly displayed in the client. The displayed interface is shown in fig. 5, and fig. 5 illustrates the search result displayed on the display interface. The display device shown in fig. 5 is a desktop computer, and the desktop computer may be replaced by a mobile phone, a tablet computer, a notebook computer, a virtual reality and other intelligent devices.

Optionally, generating the search result in response to the target keyword comprises: sequencing a plurality of pieces of information in a first information set according to a first target condition to obtain a sequencing result, wherein the first target condition comprises the correlation degree of each piece of information in the first information set and a target keyword and the release time of each piece of information; detecting information, with the similarity meeting a second target condition, in the first information set and the second information set to obtain a third information set; and adjusting the sequence of the sequencing result by using the information of the third information set to obtain a retrieval result, wherein the information in the third information set in the retrieval result is used as the first part of information.

As shown in fig. 6, a first information set is obtained by searching in the first data cluster using the target keyword; and sorting the information in the first information set according to the relevancy and the release time. The result of sorting the first set of information is shown in fig. 3. In fig. 3, the publishing times of the information (1) to the information (4) are 14:40 of 2017-8-23, 14:24 of 2017-8-23, 13:44 of 2017-8-23, and 09:41 of 2017-8-23 in sequence, and the titles of the information (1) to the information (4) all include "shenzhen", which means that the ordering of the first information set is performed according to the correlation with the target keyword and the publishing time, and the closer the publishing time is, the earlier the position of information presentation is.

As shown in fig. 6, the second information set is obtained by searching in the second data cluster by using the target keyword. And searching information which is similar to the information of the second information set in the semanteme from the first information set by utilizing semantic retrieval to obtain a third information set. Specifically, the same information as that in the second information set or information with similarity larger than a certain value is searched in the first information set. And adjusting the sorting result of the first information set by using the information in the third information set, and taking the information in the third information set as the first part of information to be adjusted to the front of the sorting result shown in the figure 3.

Fig. 4 shows the search results after adjusting the ranking, and the distribution time of the information (1) to the information (4) after adjusting the ranking is sequentially: 2017-8-2314: 27, 2017-8-2312: 50, 2017-8-2314: 40 and 2017-8-2311: 47, it can be seen that the sorted retrieval results do not take the release time as a main sorting part, but refer to the current hit information, so that the hit information is displayed at a front position and is more easily seen by a user.

It should be noted that the search result shown in this embodiment is information in the first information set, and the second information set is used to adjust the display position of the information in the first information set, and is not used for displaying the search result. That is, the final presented search result is from the first set of information.

Optionally, the detecting information in the first information set whose similarity to that in the second information set satisfies the second target condition, and obtaining the third information set includes: respectively expressing the information in the second information set and the information in the first information set by adopting vectors; similarity calculation is carried out on the information in the second information set and the information in the first information set, which are expressed by the vectors, so that the similarity between the information in the second information set and the information in the first information set is obtained; and when the similarity is greater than or equal to the target threshold, determining that the similarity meets a second target condition, wherein the greater the value of the similarity, the more similar the related information with the similarity is.

And when comparing the semantic similarity between the information in the second information set and the information in the first information set, using a word2vec tool. The word2vec tool is a tool that converts words into vector form using a deep learning model. In the embodiment, text content is converted into vector expression in a vector space, and similarity in a quantity space is further calculated to represent the semantic similarity of the text. When the word2vec tool is used, a word2vec vector corresponding to each word is trained by using massive news titles and texts in advance, then a word2vec model dictionary is loaded on line, and the similarity between the information of the first information set and the information of the second information set is calculated. And assuming that the information of the second information set is W, finding news with similarity larger than a threshold value with the information W of the second information set from the first information set, and arranging the news at the front.

The similarity comparison using the word2vec tool may be replaced by other tools for calculating semantic similarity, such as a chapter-level LDA (document theme model), LSI (semantic indexing) tool, and the like.

By the method, the existing search scheme can be quickly expanded, and the ranking result of popular news search is optimized. The scheme can access to any other news search service by maintaining a general second data cluster, and realizes effect optimization by adjusting the information sequencing of the first information set through the information of the second information set.

The embodiment of the invention also provides an information retrieval method. The information retrieval method may be performed at the client.
