    Abstract: A system is provided that includes a server having a first engine, a second engine, a search word warehouse, and a purchasing engine. The first engine (i) maps topics to product features of products using a topic hotness method which computes a hotness degree of a product on a topic from (a) product identifiers, (b) product features, (c) customer comments, and (d) topics with relevant key words, and (ii) builds a model providing a relevance degree of a topic to a product feature. The model is built based on the hotness degree. The second engine extracts remarkable topics based on product features using a method applied to the relevance degree of the topic to the product feature to identify remarkable topics for each product. The search word warehouse stores the remarkable topics for each product. The purchasing engine conducts purchases of products identified in searches using the remarkable topics.

    Abstract: A computer receives a first audio signal that is acquired by a first user device used by a first user in a conference and a second audio signal that is acquired by a second user device used by a second user in the conference. The computer processes the first audio signal based on the second audio signal to improve quality of the first audio signal, and sends the processed first audio signal to the conference.

    Abstract: A system, method, and computer program product provides a way to separate connected or adhered adjacent characters of a digital image for license plate recognition. As a threshold processing, the method performs a recognition of character adhesion by obtaining character parameters using an image processor. The parameters include a horizontal max crossing and a ratio of width and height. A first rule-based module is used responsive to the character parameters to distinguish the adhered characters (character adhesions) that are easy to judge, leaving the uncertain part to a character adhesion classifier model for discrimination. Character adhesion data is obtained by data augmentation including the adding of a random distance between two single characters to create class like adhered characters. Then the character adhesion classifier model of single character and character adhesion data is trained. Any uncertain part can be distinguished by the trained character adhesion classifier model.
