Entity disambiguation resolves which names, words, or phrases in text correspond to distinct persons, organizations, locations, or other entities in the context of an entire corpus. The invention is based largely on language-independent algorithms. Thus, it is applicable not only to unstructured text from arbitrary human languages, but also to semi-structured data, such as citation databases and the disambiguation of named entities mentioned in wire transfer transaction records for the purpose of detecting money-laundering activity. The system uses multiple types of context as evidence for determining whether two mentions correspond to the same entity and it automatically learns the weight of evidence of each context item via corpus statistics. The invention uses multiple search keys to efficiently find pairs of mentions that correspond to the same entity, while skipping billions of unnecessary comparisons, yielding a system with very high throughput that can be applied to truly massive data.

Approximate substring indexing is accomplished by decomposing each string in a database into overlapping “positional q-grams”, sequences of a predetermined length q, and containing information regarding the “position” of each q-gram within the string (i.e., 1st q-gram, 4th q-gram, etc.). An index is then formed of the tuples of the positional q-gram data (such as, for example, a B-tree index or a hash index). Each query applied to the database is similarly parsed into a plurality of positional q-grams (of the same length), and a candidate set of matches is found. Position-directed filtering is used to remove the candidates which have the q-grams in the wrong order and / or too far apart to form a “verified” output of matching candidates. If errors are permitted (defined in terms of an edit distance between each candidate and the query), an edit distance calculation can then be performed to produce the final set of matching strings.

An improved system and method for previewing search results from a search query is provided. A search results page may provide a preview link selectable by a user to preview text on pages of a website that include terms in the search query. A user may select a preview link for one of the search results, and a request may be sent to the server to preview content of a URL in the search results. In response, the server may return content of web pages of the website that include search terms in the search query. The content may be displayed in a preview window for a user to browse. Furthermore, advertisements may also be served and displayed in the preview window. A user may then browse through the specific context in which the search terms of the query appear and may more effectively find the content desired.

A method of selecting an optimal relay node in a multi-hop radio communications network has the steps of receiving, at a particular node, detection response signals which are transmitted from a plurality of other nodes, each of which has received a detection signal, and are not addressed to the particular node, and selecting a relay node based on the received detection response signals. The detection response signal includes, for example, an actual parameter in a node which transmits the detection response signal, and an optimum parameter for use as a criterion for establishing a path. The particular node selects the relay node from among those nodes which have transmitted the detection response signals each having the actual parameter equal to or larger than the optimum parameter.
