摘要:
Questions and answers associated with each other are stored in a document storage section. A clustering section classifies the answers in the document storage section into clusters based on feature vectors of the answers. When a natural language question is input by the user, a database retrieval/updating section retrieves a question similar to the input question, and presents answers associated with the retrieved question together for each cluster to the user or an expert. In addition, the database retrieval/updating section automatically updates the document storage section based on an answer selected as most appropriate by the user or the expert if selected, or based on an answer newly input by the expert if no appropriate answer is available. The natural language answer input by the expert is presented to the user as it is.

A learning and recognition machine has a major classification section for classifying an input pattern into a plurality of category groups and calculating a group belongingness to each category group and a plurality of fine classification sections for calculating a similarity within each category group. The machine causes the plurality of fine classification sections to learn in a coordinated manner by reflecting the group belongingness of the input pattern to update of a weight factor implemented in the fine classification sections, thereby allowing a recognition rate of a pattern situated at the boundary of the category groups to be improved and an effective supplemental learning to be performed.

A plurality of magnetic styli are arranged in a row for effecting a line recording. A magnetic styli are magnetized by a magnet held in contact with these styli so that a magnetic fluid attaching to the styli is protruded from each stylus to form continuous wave-like protrusions along the row of the styli. The magnetic fluid protruded from the styli is to fly or migrate as a high voltage is applied selectively between the styli and a control electrode which opposes to the styli across the recording paper, due to a Coulomb force acting on the ends of the protrusions. In consequence, a recording is made by the magnetic fluid serving as an ink on the recording paper in accordance with a recording signal. A predetermined head or height differential is preserved between the magnet and an ink tank. The magnet and the ink tank are connected to each other by means of a pipe filled with the magnetic fluid. A slight gap is formed in the connection between the pipe and the magnet. This gap, however, is completely covered and closed by the magnetic fluid attaching to the magnet so that the ambient air is prevented from coming into the pipe. A vacuum is generated in the pipe due to the aforementioned height differential to control the amount of the magnetic fluid supplied to the magnet. As the magnetic fluid is consumed progressively at the ends of the protrusions, the magnetic fluid is supplied to the protrusions from the ink tank through the pipe and the gap. In consequence, various troubles such as printing failure due to magnetic thickening of the magnetic fluid which inevitably takes place in the conventional apparatus incorporating an elongated magnet type ink supplying device, is completely eliminated to ensure a stable printing of a high quality.

A learning type signal recording and reproducing apparatus has a signal detector for detecting signals recorded on recording media, a teaching signal generator for generating reference teaching signals having predetermined waveform signal patterns, and a learning type waveform converter for generating converting rules from signals recorded on the recording medium to original signals corresponding to the recorded signals, by learning the relationship between the detection results by the signal detector of teaching signals recorded on the recording media and reference teaching signals outputted by the teaching signal generator. With this apparatus, signals can be stably reproduced even if the signals contain distortion caused by noise or difference in the recording media.

A character recognition apparatus is provided which, even when there occurs a local positional deviation of a character to be recognized, can stably recognize the character with high accuracy. For each contour point of a character image, a contouring direction code imparting unit 15 obtains a contouring direction code in which a contouring line direction of the character is quantized in four directions. A contouring direction code frequency calculation unit 16 calculates the frequency of each contouring direction code for each subregion of the character image. A contouring direction code density calculation unit 17 calculates the density of the contouring direction codes of each subregion, by using the frequency of the direction codes and the size of the respective subregion. A contouring direction code space blurring unit 18 conducts a weighted addition on each of the obtained contouring direction codes by adding, with a predetermined weight coefficient, the contouring direction code densities of neighbor subregions which are adjacent to the respective subregion with the subregion as the center and in a direction perpendicular to that of each of the contouring direction codes.
