TW200411462A - A method for matching information exchange on network - Google Patents

Abstract

A method for matching information exchange on network which can avoid inconvenience and problems usually met nowadays when matching information demand with information supply. For example, traditional searching keywords is not an appropriate tool for expressing one's information demand because text searching consideration is behind. Another example, selecting appropriate information exchange object is difficult because of information overloading from keyword searching. This invention first proposes "descriptive words/terms set" as the way to express one's information demand or supply; then uses a server to catch "descriptive words/terms set" from both information demand and supply; then makes use of "descriptive words/terms set" to match information demand and supply. One way of matching is to use keywords to search "descriptive words/terms set" and select appropriate exchanging object from the searching result. The other way of matching is to count the similarities between the information-demand's and the information-supply's "descriptive words/terms set" to determine the appropriate exchanging object.

Description

200411462 V. Description of the invention (1) <Technical Field> The present invention relates to a method for information seeking and information providing transactions on a computer network, especially when information seeking and information providing transactions are matched on a computer network. Description, information seeking, and method of selecting transactions between feeds. <Prior art>

At present, on the Internet, individuals who do not know each other can use the intermediary server device to conduct information seeking and providing transactions, such as WWW website Liu Ku, bulletin board, job agency website, ezpeer, e D ο nkey, etc. ° In the matching of information seeking and providing transactions, the description of information seeking and providing information, and the selection of transaction objects between information seeking and information providing, are mainly carried out through several basic methods, but they all have some inconveniences and problems.

The first is the use of keywords to retrieve narrative documents, such as the WWW website Liu Lan. In this way, for the description of information seeking, the information seeker is expressed by the keyword string combination of AND, OR, NOT; for the description of the information providing, the information provider is expressed by narrative documents; and for the information seeking The choice of the transaction object between the information provider and the information provider is a full-text search of the narrative documents provided by the information provider with the keyword string of AND, OR, NOT, and then from the retrieved narrative documents. Selection of transaction objects. There are three problems with this approach. First, the keyword strings combined with AND, OR, and NOT cannot really express the meaning of information seeking, because the underlying purpose and function behind it are for full-text search;

Page 6 200411462 V. Description of the invention (2)

In addition, full-text search often retrieves a large amount of narrative documents. These large amounts of narrative documents cannot be directly sorted and distinguished by fitness. It takes a lot of time and manpower to find the information that is actually sought; in addition, In this way, the information provider cannot take the initiative to select the transaction target for the information seeking. The second is the use of database processing methods, such as job agencies, dating sites, in this way, the description of information seeking, information seekers are expressed in the form of data records, for the description of information providers, information providers It is also expressed in the form of data records; and the selection of transaction objects between information seeking and providing is performed by means of database query. The problem with this method is mainly that the range and format of the data record are fixed. The information cannot be freely expressed and the information provided. Therefore, the scope of application is limited. The third method is to use a keyword to search the directory name and file name, such as eDonkey. In this way, for the description of information seeking, the information seeker is expressed by a keyword string, for the description of the information providing, the information provider is expressed by a directory name and a file name; and for the transaction object between the information seeking and providing The selection of is by the information seeker using a keyword string to search the directory name and file name provided by the information provider, and then select the transaction object from the retrieved directory name and file name. There are two problems with this approach. First, the ability to express information seeking and providing information is limited; further, the information provider cannot actively choose the transaction object for information seeking. In addition, there are many advanced research developments, such as intelligent agents, which can use user interest files to compare similarity with the provided documents for prioritization, and can use genetic algorithms to improve interest files. These agents

Page 7 200411462 V. Description of the invention (3) The system can improve some of the problems mentioned above, but they are still based on these basic methods. In summary, they all have their applications, but they also have their own problems and limitations due to the lack of functional features. Some of the shortcomings of the order include: limited expression of information seeking and information providing; information providers cannot actively query and match information seeking; it is difficult to judge the suitability of transaction objects from the results of the inquiry; The results are difficult to sort quantitatively. The purpose of the information network on the road is to provide a system of supply and withdrawal, which is clearly stated in &gt; Appreciation of the Contents &lt; Combining Pledges, Do Not Want to Make It Easy, Delivering Time to Provide Information and Supply and Demand to Seek Information Assets may ask for their information. Those who are in charge of the asset law jointly use the exchange to make changes, and when the time is right, they must not be restricted. In the case of Dacau's thinking, there is an ability to do word searches or texts based on the existing concept, which can be used in the construction of the syndication, or the information can be easily exchanged for the transaction information. Lu Dingyi.com selects the hybrid fruit as soon as it is used for confession and inspection, and the incumbent 9 who uses it for the purpose of the other, and the effective Xu Youming will issue the formula, and it is more legal to do so. The purpose of a supply and delivery system of the E-Communication Information Network is to publish the information provided by the Minda of the Renewal Service. The information provided by the option is similar to the long-to-redundant comparison. In the same way, one party must not allow it if it is used. At the same time, the party of the law and the party has made a clear statement on the publication of the information on the network.

Page 8 200411462 5. The method of invention description (4) includes: first, providing a set of descriptive words as an expression of information seeking or information providing; and then, using an intermediary servo device to receive both information seeking and information providers Information seeking and descriptive word sets of information feeds; then, use information seeking or descriptive word sets of information feeds to match information seeking and information transactions. One of the ways of matching is by information seeking Or information provider, using the keywords of AND, OR, and NOT keywords, to perform a full-text search query on the intermediary server's information seeking or descriptive word set of the information feed, and then make the transaction results of the query results. Select and complete the matching of information seeking and feed transactions. Another way of matching is to compare the descriptive word set of a certain information with the descriptive word set of each information source to compare the similarity to select the transaction object or descriptiveness of a certain information source. The word set is compared with the descriptive word set of each information seeking, and the similarity comparison is performed to select the transaction object, and the matching of the information seeking and the information providing transaction is completed. <Embodiment> In order to explain the technical content, features and effects of the present invention, a preferred embodiment is described below, with the illustration as follows. Graphic description: The first figure is a descriptive word set provided by the present invention. The second figure is a set of descriptive words provided by the intermediary server to receive information seeking and information provided by the present invention. The third figure is a descriptive word set of the full-text search query of the present invention

200411462 V. Description of the invention (5) Sample result. The fourth figure is a sorted result of a result example of the descriptive word set of the full-text search query according to the present invention. The fifth figure is a calculation formula for the similarity comparison of the descriptive word set of information seeking and providing according to the present invention. The sixth figure is a flow of using the present invention.

A method for matching information transactions on the Internet according to the present invention. First, a descriptive word set is provided as an expression of an information seeker for an information seeker or an expression of an information provider for an information feed. Please refer to the first figure for a descriptive word The word set 1 1 is a string of words separated by the symbol 1 2 1 3 1 4 1 5 1 6 1 7 These words can be a single word 13 or a multi-word word 14; these words can be The words 15 16 with the 'NOT' symbol become the opposite of the original words; these words can be several words separated by '0R' 1 7 which means that these words have the same meaning , You can choose one or they can be interoperable; these words can be given a weight of 18 to indicate the importance of the word in the entire descriptive word set 1 1. This descriptive set of words 11 is used to express the meaning of information seeking or information providing. It is not used for full-text retrieval of documents.

Then, referring to the second figure, the intermediary servo device 2 1 receives the information sent by the information seeker 2 2 for a descriptive word set 2 3 and the information feed provided by the information provider 2 4 with a descriptive word set 2 5. Then, use the descriptive word set of information seek or information feed to match the transaction needs between information seek and information feed.

One of the formulas is a full-text search query performed by an information seeker or information provider with a keyword string consisting of AND, OR, and NOT on the descriptive word set of the information seeking or information feed of the intermediary server. Referring to the third figure, which is a sample result 3 1 of a full-text search query. Since an information seeker or information provider uses a descriptive word set, it is not necessary to use it as a keyword when expressing information seeking or providing information. Full-text search is based on thinking, and can be used to express the connotation of information seeking or information providing, so it can make a considerable degree of clear expression of information seeking or information providing, and it does not need to be verbal narrative like a document. This has It helps information seekers or information providers to more easily determine the appropriateness of transaction objects from the query results and make selections of transaction objects to complete the match between information seeking and information providing transactions. In addition, due to descriptive terms The collection is a text string, which allows us to directly sort it. Please refer to the fourth figure, which is the aforementioned full-text search query Result Example 3 1 A sorting result 4 1, because it is a string order, the descriptive word set can be arranged in alphabetical order, and the same and similar descriptive word set will form an aggregate 4 2, information seeker or information Providers will be able to easily locate the descriptive words that are suitable for them, making the selection of transaction objects easier, and making the matching of information seeking and information providing transactions more efficient. In addition to the aforementioned matching method, another method of matching is to compare the descriptive word set of a certain information with the descriptive word set of each information source to compare similarities to select a transaction object, or The descriptive word set of an information feed is compared with the descriptive word set sought by each information to select the transaction object. Please refer to the fifth figure, which is the calculation formula 5 1 and the example 5 2 for the similarity comparison. The calculation formula is used to compare two

Page 11 200411462 V. Description of the invention (7) Similarity of documents For information seeking, the series of similarity thresholds for each information series are the same as those of the present invention, and are often used by those who are commonly used. For your benefit, you can take a descriptive score of a certain resource, this information providing device 21 vocabulary, test, after going to the intermediary, the lieutenant general can use the easy-to-use process of the words, after the servo, the sexual words are used The description of the user can decide whether to save the edited word using the editing server, and refer to the device user ’s set of words that determine whether or not the transaction is a transaction. The network allows users to use the information search device 21 to provide information. One of the functional standards and accurate and effective inventions of the dictionary is one of the inventions. According to the sixth picture, it can be saved and reorganized. You can decide to edit and decide whether to use the word collection and merge information when searching for words. Demand or supply of energy can be stored in a variety of ways. The key selection group of the first management group can be summarized according to the information of the intermediary information agency. The information description and the gradual cultural road can be organized first. The user of the transaction servo-information organization who provides sexual literacy groups with the similarity of the habitual similarity ratio is selected, and the information matching device 21 is used to find the descriptive word set of the described description. One way is to calculate the descriptive words in such a way, and provide the methods to complete them. The download news provides the use of descriptive words, descriptive and descriptive, and will eventually be calculated as 51. It also includes a set of intermediary description words, long-term words, word funding, and a score that seeks to include another servo word as a reference. The use of the set of information and transaction matching methods, users can decide whether to download the description Sexual word set 6 1-6 2; then the description of the information seeking or the feed is referred to the server 6 3-6 5; The information provided by the subject 6 6-6 7; then, the user provided a set of descriptive words

Page 12 200411462 V. Description of the invention (8) The similarity comparison must be limited according to the features and functions of the present invention, because it is convenient, effective, and easy to match, rather than the case name, so when using descriptiveness with similarity The degree of comparison means information seeks and moves to choose the intersection. This makes one of the choices of information, first of all; the second is the sub-transaction network that enables the lengthy comparison of words that do not make the information easy to compare. It is set with and without more methods, it is too lacking to provide images, objects, and objects. It is based on descriptive cables to seek or based on the efficiency of the selected table instead of efficiency, which are described and knowledgeable. -6 〇 〇 News transaction word set at the end of the document to think about the information and then describe the meaning of the document to select the long-term change of the subject of the description of the words to share with the use of matching, test, but also for selection Complementary and arguable narratives, appropriate to complete the actual vocabulary list similarity of the document narrative, compared to the automatic method, which does not need to be easy to order or easy to describe transactions; It is self-sustaining, and there is an image related to the image to describe in a simple picture; matching this enables the two parties to do anything that can be used by anyone who is familiar with the main record of this book. Creative use of the scope of this workshop. As the technical content, it is modified, and many keys are changed to make the material more up-to-date, and the crosswords with short words are more complete. They are similar, because they can be selected by the master. Are
