Abstract
Abstract An input processing system inputs character string data including kanji characters and corresponding to phonetic data by entering phonetic data. An input device sequentially inputs phonetic data and sentence end data. A conversion section includes a conversion processor, a syntactic analyzer, and a priority order alterator. The conversion processor sequentially converts character string data in a predetermined conversion unit. If single phonetic data includes a plurality of conversion possibilities in the predetermined conversion unit, character string data is selected according to a predetermined priority order, thereby obtaining character string data (including kanji characters) corresponding to input phonetic data. The syntactic analyzer performs syntactic analysis of a sentence consisting of the character string data in response to sentence end data. The priority alterator alters the priority orders of the conversion possibilities corresponding to identical phonetic data for the conversion processor according to syntactic analysis results, and alters the already selected possibilities as needed. The character string data from the conversion processor in the conversion section is displayed on a diplay.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
210 words
A phonetic data-to-kanji characters converter for converting character string data including Kanji characters, comprising: input means for inputting phonetic data and sentence end data representing an end of a sentence; conversion processing means for sequentially converting the phonetic data input by said input means into character string data in a predetermined train of the phonetic data, selecting character string data having the highest priority according to a predetermined priority order in the predetermined train of the phonetic data if a plurality of conversion possibilities are present, and obtaining the character string data which corresponds to the phonetic data; storing means for storing, in accordance with said priority order, all of the character string data obtained by said conversion processing means; syntactic analyzing means for analyzing syntactic relations in the character string data from said conversion processing means in response to the sentence end data from said input means; priority order altering means for altering, based on the analyzed syntactic relations, the priority order of the plurality of conversion possibilities corresponding to homonymic data during the processing of said conversion processing means, and altering selection of the character string data according to an altered priority order; and output means for sequentially displaying the character string input from said conversion processing means.
Claim 2
Dependent Claim
210 words
A phonetic data-to-kanji characters converter for converting character string data including Kanji characters, comprising: input means for inputting phonetic data and sentence end data representing an end of a sentence; conversion processing means for sequentially converting the phonetic data input by said input means into character string data in a predetermined train of the phonetic data, selecting character string data having the highest priority according to a predetermined priority order in the predetermined train of the phonetic data if a plurality of conversion possibilities are present, and obtaining the character string data which corresponds to the phonetic data; storing means for storing, in accordance with said priority order, all of the character string data obtained by said conversion processing means; syntactic analyzing means for analyzing syntactic relations in the character string data from said conversion processing means in response to the sentence end data from said input means; priority order altering means for altering, based on the analyzed syntactic relations, the priority order of the plurality of conversion possibilities corresponding to homonymic data during the processing of said conversion processing means, and altering selection of the character string data according to an altered priority order; and output means for sequentially displaying the character string input from said conversion processing means.
