摘要:
A repository contains objects representing entities. The objects also include facts about the represented entities. The facts are derived from source documents. A synonymous name of an object is determined by identifying a source document from which one or more facts of the entity represented by the object were derived, identifying a plurality of linking documents that link to the source document through hyperlinks, each hyperlink having an anchor text, processing the anchor texts in the plurality of linking documents to generate a collection of synonym candidates for the entity represented by the object, and selecting a synonymous name for the entity represented by the object from the collection of synonym candidates.

A domain-specific sentiment classifier that can be used to score the polarity and magnitude of sentiment expressed by domain-specific documents is created. A domain-independent sentiment lexicon is established and a classifier uses the lexicon to score sentiment of domain-specific documents. Sets of high-sentiment documents having positive and negative polarities are identified. The n-grams within the high-sentiment documents are filtered to remove extremely common n-grams. The filtered n-grams are saved as a domain-specific sentiment lexicon and are used as features in a model. The model is trained using a set of training documents which may be manually or automatically labeled as to their overall sentiment to produce sentiment scores for the n-grams in the domain-specific sentiment lexicon. This lexicon is used by the domain-specific sentiment classifier.

摘要:
A set of objects having facts is established. Facts of objects having positions in an order are identified. Some facts explicitly describe the positions in the linear order, while are facts do not explicitly describe the positions. The facts are presented in the order on a linear graph, such as a timeline. Facts of the objects describing geographic positions are presented on a map.

Metadata is used to determine rules that can be applied to facts. In one embodiment, correlations are identified among types of objects and the attributes of the facts associated with those objects. In another embodiment, correlations are identified among types of objects, the attributes of the facts associated with the objects, and the format and/or range of the values of the facts having those attributes. When a correlation exists between objects of a given type and the attributes of the facts associated with objects of that type, a rule is created for objects of that type. The rule is applied to objects of the given type.
摘要:
An adaptive compression technique which is an improvement to Lempel-Ziv (LZ) compression techniques, both as applied for purposes of reducing required storage space and for reducing the transmission time associated with transferring data from point to point. Pre-filled compression dictionaries are utilized to address the problem with prior Lempel-Ziv techniques in which the compression software starts with an empty compression dictionary, whereby little compression is achieved until the dictionary has been filled with sequences common in the data being compressed. In accordance with the invention, the compression dictionary is pre-filled, prior to the beginning of the data compression, with letter sequences, words and/or phrases frequent in the domain from which the data being compressed is drawn. The letter sequences, words, and/or phrases used in the pre-filled compression dictionary may be determined by statistically sampling text data from the same genre of text. Multiple pre-filled dictionaries may be utilized by the compression software at the beginning of the compression process, where the most appropriate dictionary for maximum compression is identified and used to compress the current data. These modifications are made to any of the known Lempel-Ziv compression techniques based on the variants detailed in 1977 and 1978 articles by Ziv and Lempel.
摘要:
A multi-source input and playback utility that accepts inputs from various sources, transcribes the inputs as text, and plays aloud user-selected portions of the text is disclosed. The user may select a portion of the text and request audio playback thereof. The utility examines each transcribed word in the selected text. If stored audio data is associated with a given word, that audio data is retrieved and played. If no audio data is associated, then a textto-speech entry or series of entries is retrieved and played instead.

A background audio recovery system displays an inactive status indicator for a speech recognition program module in an application program. To prevent losses of dictated speech when a speech recognition program module is inadvertently assigned to an inactive mode, the background audio recovery system determines whether an audio input device is receiving audio. If audio is being received by the audio input device, the background audio recovery system stores the audio data for later retrieval by the user. When a user issues a command to activate the speech recognition program module, the background audio recovery system initiates a background audio program module for manipulating the stored audio data that was recorded while the speech recognition program module was assigned to an inactive mode.
