A fast access high capacity data storage system and method are disclosed, the data storage system including a disk-based storage system employing a plurality of storage surfaces. Selected storage surfaces have a plurality of independently controlled data access heads in data communication therewith, and circuitry is provided for allowing concurrent data transfers through the plurality of data access heads. Performance is further improved by monitoring frequently accessed data records and transferring them to a copy recording surface or recording surfaces less frequently used, and by moving a data access head of the plurality of data access heads to other recording surfaces to decrease access bottlenecks. The storage system further includes circuitry for averaging at least one of record length data, transfer timing data, access timing data and address data.

A recording medium is provided with a recording film having opto-magnetic characteristics formed on the substrate, with first information being recorded in advance in the form of pit strings of a phase structure. Second information is recorded over the first information through the application of a magnetic field with polarities corresponding to the second information in the presence of the irradiation of a high-power radiation beam, without damaging the record of the first information. The first and second information are produced independently and simultaneously with a single spot in the same area by use of different signal reproduction mechanisms for the first information and second information. The first information (ROM information) is reproduced as the variation in the amount (intensity) of the reflected light from the opto-magnetic recording film, and the second information (RAM information) is reproduced by detecting the rotational angle of the reflected light, based on the Kerr effect, from the opto-magnetic film concurrently with the reproduction of the first information using a single spot.

A method and a machine for generating a dictionary of address phrase expressions. One embodiment of the invention includes an apparatus for generating a dictionary of target phrases that includes an input interface for receiving as its input a first address phrase included in a list of address phrase expressions, a memory for storing a dictionary of address phrase variants, including rules for generating variants of address phrase expressions, and a processing device for generating variants of address phrases which generates a second address phrase which is different in expression from the first address phrase to output the second address phrase to a storage device holding the dictionary of target phrases, based on the input first address phrase, and the knowledge of rules about variants included in the dictionary of address phrase variants.
摘要:
An information retrieval system with good human-interface methods to give the system ease-of-use having two distinctive features with the first being visual interface and the second being natural language interpretation. The visual interface provides for visual interaction for local search and natural language interpretation provides for linguistic interaction for global search. The visual interface provides versatile views onto the contents of the knowledge base that the system has, controlling mechanisms for browsing through the knowledge base, a capability of showing relevant information for the users, and a mechanism for editing a query expression that describes information to retrieve. By using the visual interface for information retrieval, the users can easily create query expressions, by consulting and reacting with the system. The natural language interpretation makes use of a conceptual network as a knowledge-base that stores important concepts and relationships among these concepts. Based on knowledge and information represented in the conceptual network, the meaning of a noun phrase or a nominal compound which is a string of adjectives and nouns with some prepositions can be inferred. The inferred interpretation of such a noun phrase is paraphrased into an expression that the information retrieval system can handle. Therefore, the user of the system can simply describe the desired information in a language to get the desired information.

A document analysis system for determining format information of a document, wherein frames and a relationship of the frames are extracted from an image of an unmarked sample document, characters in a frame of the document are recognized, and an image structure is analyzed based on the frame and the recognized characters.
摘要:
A character stream search system using an FSA for determining at a time whether or not a plurality of character streams as search objects exist in a search character stream which undergoes a search operation and which comprises a plurality of characters expressed with codes. In the system, a collation is conducted between the search character stream and a search object character. In a case where there exists a matched search object character as a result of the collation, a state transition is carried out of a predetermined state indicated by the FSA. In a case where there does not exist a matched search object character, a failure processing to effect a state transition to a transistion destination which is determined in association with the configuration of the FSA. The following processing is completed at a count which is a predetermined upper-limit value for each character undergone the search operation.
摘要:
A picture coding system for a document image data in which a plurality of picture coding methods are subjected to a selection such that document image data is converted so as to obtain an identification code representing the selected coding method and signals obtained by coding the data. The system includes units for detecting and for accumulating code lengths of the codes converted in the respective coding methods, units for detecting and for accumulating a difference between the lengths of the respective codes obtained by the conversion achieved in the coding methods, a storage for storing therein a history of a result of the selection of the preceding coding method, and a change-over judge unit for selecting one of the plural coding methods based on information obtained from the three kinds of units.
摘要:
A digitized multilevel signal is encoded on the basis of unit combinations each including a run-length bit field indicative of run-length at each of the signal levels and a single continuation bit indicative of transition of the signal levels. The encoding is so modified that a virtual run of zero length is inserted when the transition of the signal levels at adjacent sampling points departs from a predetermined order. Polarity of the continuation bit is inverted upon every transition of the signal level.
