Abstract: A document search system that enables efficient document search regardless of the ability of a user is achieved. Document search is performed using a document search system in which database document data is stored. After first document data and second document data are input to the document search system, the document search system extracts a plurality of terms from the first document data. The extraction of the terms is performed using morphological analysis, for example. Next, the extracted terms are weighted on the basis of the second document data. For example, texts included in a document represented by the second document data are classified into first and second texts. Among the terms extracted from the first document data, the weight of the term included in the first text is set larger than the weights of the other terms. The classification of the texts can be performed in accordance with a rule basis or using machine learning. After that, the similarity of the database document data to the first document data is calculated on the basis of the weighted term.

Abstract: A proofreading system that allows a user to easily judge whether or not there is an error in writing or the like. A proofreading method using a comparison image group obtained by dividing a sentence included in a comparison document group into a plurality of first terms and converting the first terms into images is provided. Specifically, first, a sentence included in a designated document is divided into a plurality of second terms, and the appearance frequency in the comparison document group of the plurality of second terms are obtained. Next, the second term with the appearance frequency lower than or equal to a threshold value of the plurality of second terms are imaged to obtain a verification image. After that, similarity degrees between the verification image and comparison images included in the comparison image group are obtained, and the first term represented by the comparison image with the highest similarity degree of the comparison images is presented. The presentation is performed by displaying that the second term represented by the verification image can be an error in writing of the first term represented by the comparison image having a high similarity degree with the verification image.

Abstract: Provided are a voucher verification method and a voucher verification system for automatically checking agreement between a voucher and accounting data. A processing portion receives accounting data, voucher image data, and text data, extracts a local image feature value from the voucher image data, generates, using a learned determination model, a first vector based on the accounting data and a second vector based on the local image feature value and the text data, calculates similarity between the first vector and the second vector, determines whether the accounting data agrees with the voucher using the calculated similarity, and outputs a determination result. Note that the text data is data extracted from the voucher image data by optical character recognition.

Abstract: A lithium ion secondary battery includes a positive electrode, a negative electrode, and an electrolyte provided between the positive electrode and the negative electrode. The positive electrode includes a positive electrode current collector and a positive electrode active material layer over the positive electrode current collector. The positive electrode active material layer includes a plurality of lithium-containing composite oxides each of which is expressed by LiMPO4 (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)) that is a general formula. The lithium-containing composite oxide is a flat single crystal particle in which the length in the b-axis direction is shorter than each of the lengths in the a-axis direction and the c-axis direction. The lithium-containing composite oxide is provided over the positive electrode current collector so that the b-axis of the single crystal particle intersects with the surface of the positive electrode current collector.
