Predefined relation items on paths traversing predefined entities of a knowledge base are collected and feature sets are assembled from the collected relation items. A classifier is computed for the feature sets and a relation score of a query pair of the entities is computed using the classifier.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method comprising: collecting predefined relation items on paths traversing predefined entities of a knowledge base; assembling feature sets from the collected relation items; computing a classifier for the feature sets; computing a relation score of a query pair of the entities using the classifier. 2. The method of claim 1, wherein collecting the relation items comprises: collecting the relation items on each of the paths defined between the entities including at least one path that traverses another entity. 3. The method of claim 1, wherein assembling the feature sets comprises: forming generalized path statements from the relational items collected from the respective paths; and providing the generalized path statements as the feature set. 4. The method of claim 3, wherein forming the generalized path statements comprises: replacing entity names on each of the paths with respective variables; and interposing the variables between corresponding relational items to form the generalized path statement. 5. The method of claim 1, wherein the paths include positive and negative relations. 6. The method of claim 1, wherein the entities and relation items in the knowledge base are indicative of medical entities and relations.
