The source screening method can be executed by terminal 102 or server 104, or by terminal 102 and server 104 working together.

[0048] The terminal 102 may be a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, IoT device, or portable wearable device. IoT device may be a smart speaker, smart TV, smart air conditioner, or smart car device. Portable wearable device may be a smart watch, smart bracelet, or head-mounted device.

[0049] The server 104 may be an independent physical server or a service node in a blockchain system, where each service node in the blockchain system forms a peer-to-peer network.

[0050] In addition, server 104 can also be a server cluster composed of multiple physical servers, and can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0051] The terminal 102 and the server 104 may be connected via Bluetooth, USB (Universal Serial Bus), a network or other communication connection methods, which are not limited in the present invention.

[0052] In some embodiments, as Figure 2 As shown, a method for filtering information sources is provided. Figure 1 The server or terminal in the Figure 1 The server and terminal in the method are executed in collaboration. Figure 1 The following steps are used as an example to illustrate the terminal execution in .

[0053] Step S100: Obtain domain keywords corresponding to the target domain, and search for potential information sources based on the domain keywords.

[0054] Combine Figure 3As shown in , this embodiment first obtains the domain keywords of the target field. The target field is used to determine the scope of the information source search. For example, if the target field is the semiconductor integrated circuit field, the information source for subsequent search and analysis is the information source in the semiconductor integrated circuit field. The domain keywords are information closely related to the target field in this embodiment. They can be technical terms well-known to the public in the target field, or they can be descriptive words that often appear in the target field, such as slogans. After determining the domain keywords, this embodiment can search for potential information sources based on the domain keywords. In actual application, this embodiment can use web crawler technology to crawl potential information sources based on domain keywords. In addition, the domain keywords of this embodiment can be one or more. When there are multiple domain keywords, this embodiment can search the domain keywords in combination, or use the domain keywords in sequence for search. When searching using domain keywords in sequence, this embodiment can set priority information for each domain keyword and search in sequence based on the priority information.

[0055] In one implementation, this embodiment includes the following steps when obtaining domain keywords:

[0056] Step S101: Obtain network search records corresponding to the target domain;

[0057] Step S102: determining the search frequency of each search term based on the network search records;

[0058] Step S103: Determine the domain keyword based on the search frequency.

[0059] Specifically, this embodiment may first obtain the network search records corresponding to the target domain, and the network search records may be traces of search terms under the target domain. This embodiment may obtain the search records within a preset time period, and then determine the search frequency of each search term within the preset time period. The higher the search frequency, the more times the search term is used, and the more it can reflect the characteristics of the target domain. Therefore, this embodiment may use the search term with the highest search frequency or a search frequency higher than a preset value as a domain keyword. In another implementation method, this embodiment may also determine the number of searches for each search term within a preset time period. The more searches a certain search term has, the more it can reflect the characteristics of the target domain. Therefore, this embodiment may use the search term with the highest search frequency or a search frequency higher than a preset value as a domain keyword. After determining the domain keyword, this embodiment may search for potential information sources based on the domain keyword.

[0060] Step S200: Integrate and classify the potential information sources to obtain candidate information sources.

[0061] After searching for potential information sources, since there are some non-authoritative and duplicate information sources among the potential information sources, in order to quickly screen out high-quality information sources, this embodiment can integrate and classify the potential information sources, with the goal of integrating similar potential information sources and finally obtaining candidate information sources.

[0062] In one implementation, this embodiment includes the following steps when integrating and classifying potential information sources:

[0063] Step S201: Determine attribute information of the potential information source, wherein the attribute information is used to reflect key information of the potential information source;

[0064] Step S202: Based on the attribute information, the potential information sources are integrated and classified to obtain the candidate information sources.

[0065] Specifically, this embodiment first obtains the attribute information of the potential source, and the attribute information is used to reflect the key information in the potential source. The key information can be the source information of the potential source, such as the source is news website A or forum B. The key information can also be the content in the potential source, such as the development prospects of the semiconductor industry or the release of a list of well-known companies in the semiconductor industry. After determining the attribute information, this embodiment can integrate and classify the potential sources based on the attribute information to obtain the candidate sources. In this embodiment, the process of integrating and classifying potential sources is essentially a deduplication process, and the determined attribute information can reflect the characteristics of the potential source to a certain extent. Therefore, this embodiment can analyze the attribute information of the potential source based on the large language model, so as to quickly determine the candidate source.

[0066] Specifically, based on the attribute information, a large language model is used to determine the similarity between the potential sources; then, based on the similarity, the potential sources are integrated and classified to obtain the candidate sources. For example, when the attribute information is the source information of the potential source, it can be combined with the release time of the potential source to determine that the potential sources released on the same news website or the same forum at the same time (or the same time period) are similar. At this time, the similar ones can be integrated together to obtain the candidate sources. In another implementation method, this embodiment can also use a large language model to determine the similarity between the potential sources based on the content in the potential sources reflected by the attribute information. For example, the title or subject of each potential source is obtained to compare whether the title or subject is similar, and then similar potential sources are integrated together to obtain candidate sources.

[0067] In addition, this embodiment can also establish a knowledge graph of potential sources in the target field based on the attribute information. The knowledge graph can be used to reflect the correlation between potential sources, and based on the correlation, the potential sources can be integrated and classified. In specific applications, this embodiment can perform feature extraction based on the content of the potential sources reflected in the attribute information, extract the feature information involved in each attribute information, such as a person's name, company information or key technical terms, etc. Based on the extracted characteristic information, a large language model is used to determine the correlation between the feature information, and then the correlation between the attribute information is obtained, thereby obtaining the correlation between potential sources, and then establishing a knowledge graph. By establishing a knowledge graph, this embodiment can more accurately analyze the relationship between potential sources, which is conducive to integrating and classifying similar or similar potential sources, thereby obtaining candidate sources.

[0068] Step S300: Perform quality assessment on the candidate information sources to obtain a quality assessment result, and determine a target information source based on the quality assessment result.

[0069] After obtaining the candidate signal sources, this embodiment may perform a quality assessment on the candidate signal sources to obtain a quality assessment result. The purpose of the quality assessment is to screen out high-quality signal sources from the candidate signal sources. To this end, this embodiment may perform a quality assessment on the candidate signal sources from multiple dimensions to obtain a high-quality target signal source.

[0070] In one implementation, the quality assessment of candidate information sources in this embodiment includes the following steps:

[0071] Step S301: Score the candidate information source to obtain score information of the candidate information source;

[0072] Step S302: Obtain a quality evaluation result of the candidate information source based on the scoring information.

[0073] Specifically, this embodiment can score candidate sources, and the scoring dimension can be the publisher information and / or browsing information of the candidate source. The credibility and authority of candidate sources published by different publishers are also different. Therefore, this embodiment can pre-set weight information for each type of publisher information. After determining the publisher information of the candidate source, it can be scored based on the weight information corresponding to the publisher information to obtain the scoring information of the candidate source. There are many contents that can be reflected in the browsing information. The browsing information can include the comment information, visit volume, etc. of the candidate source. The more comment information or visit volume, the more credible or popular the candidate source is. Therefore, this embodiment can also set weight information corresponding to different amounts of comment information or visit volume, and then obtain the scoring information of the candidate source based on the weight information. After obtaining the scoring information, this embodiment can obtain the quality assessment result of the candidate source, and the quality assessment result is the specific score of the candidate source.

[0074] In another implementation, this embodiment can also profile the users of a candidate source based on the comments from that source and determine their user information. This user information can reflect information such as their occupation and educational background. Specifically, this embodiment can collect the content described in the user's comments and their profile on websites or forums to create a user profile and obtain the user information. After determining the user's user information, this embodiment can match the user's user information with a database of talent in the target field to determine whether the user is a skilled person in the target field. This embodiment can analyze all comments under each candidate source to identify all skilled people who have posted comments under each candidate source, and then score the candidate source based on the number of skilled people who have posted comments. For example, the more skilled people who have posted comments under a candidate source, the higher the score for that source. Similarly, this embodiment can also utilize the aforementioned user profiling technology to analyze the type of publisher information in a candidate source, thereby quickly identifying the publisher. It can be seen that this embodiment evaluates candidate sources by determining their scoring information, and the evaluation dimensions include publisher information and / or browsing information of the candidate sources. Evaluation is performed from multiple dimensions, which is more objective and accurate, and also facilitates screening out high-quality target sources.

[0075] After obtaining the quality assessment results of each candidate source, the candidate source with the highest score can be directly used as the target source, or the candidate source with a score higher than a preset threshold or a high ranking can be used as the target source to generate a source list, thus completing the screening of high-quality sources. Furthermore, after screening out the target source, this embodiment determines the source keyword based on the target source; based on the source keyword, the domain keyword is updated, so that the potential source can be re-searched based on the updated domain keyword, and the source screening can be re-performed to improve the accuracy of the source screening. This embodiment constructs a closed-loop system in which domain keywords and source quality drive each other. Specifically, potential sources are captured through domain keywords, the quality of potential sources is evaluated, and domain keywords are iterated to form a spiral optimization path, which solves the limitations of traditional single searches. In addition, in this embodiment, the domain keywords are iteratively updated. Whenever the target source is screened out, the source keywords can be re-summarized based on the target source, and then the domain keywords can be updated using the source keywords. During an update, this embodiment can match source keywords with domain keywords. If there are multiple source keywords and multiple domain keywords, the source keywords and domain keywords are retrieved, and the words that differ from the domain keywords in the source keywords are directly added to the domain keywords to update the domain keywords. Furthermore, this embodiment can also construct a keyword library based on the domain keywords. In addition to the domain keywords of the target domain, this keyword library also includes domain keywords for other domains. All domain keywords are divided and stored by domain for easy access.

[0076] In summary, this embodiment first obtains the domain keywords corresponding to the target domain, and searches for potential information sources based on the domain keywords. Then, the potential information sources are integrated and classified to obtain candidate information sources. Finally, the quality of the candidate information sources is evaluated to obtain a quality evaluation result, and the target information source is determined based on the quality evaluation result. This embodiment first searches for potential information sources, then analyzes the potential information sources to determine candidate information sources, and then evaluates the candidate information sources to screen out the target information sources. It can be seen that this application can achieve information source screening based on the dual screening mechanism to obtain higher quality information sources.
