Patent number: 10659628Abstract: An embodiment of the invention has been made to solve a problem that it is impossible to store externally transmitted job information if a printer apparatus is in a hard-off state and it is, therefore, necessary to store the job information in an external apparatus on the transmission side. In the embodiment, a wireless communication unit which can transmit/receive data even if no power is supplied receives job information from an external terminal, and stores it in a non-volatile memory. When an information processing apparatus is supplied with power, and enters a normal activation state, it executes the job stored in the non-volatile memory.Type: GrantFiled: August 1, 2017Date of Patent: May 19, 2020Assignee: Canon Kabushiki KaishaInventor: Kazunori Yamauchi

Patent number: 10628525Abstract: Detecting and incorporating formatting characteristics within natural language processing analytics. Source documents are ingested and the markup formatting language is identified by the program. Once identified, the markup language is parsed and examined for formatting characteristics, embedded notes, comments and other metadata. The formatting characteristics of the plain text are extracted, along with the plain text, and converted into a common analysis structure (CAS), or CAS-equivalent structure, which annotates the natural language text together with its respective formatting characteristics. The CAS or CAS-equivalent structures are stored and sent to a natural language processing pipeline for further analysis via complex algorithms and rules. The natural language processing results data are curated to reflect meaningful analysis of the extracted CAS or CAS-equivalent structure.Type: GrantFiled: May 17, 2017Date of Patent: April 21, 2020Assignee: International Business Machines CorporationInventors: Patrick W.
