Abstract: A method of updating the content of an electronic document includes receiving a metadata file by a server, the metadata file including document information regarding a subject matter of the electronic document and reference information regarding other sources of content referenced in the electronic document, and searching the other sources of content for corresponding information to the subject matter of the electronic document. The method also includes analyzing semantically the corresponding information, comparing the corresponding information to the electronic document to find inconsistencies, and generating an enriched metadata file including updated content suggested for the electronic document based on the inconsistencies.

Abstract: An approach is described with respect to dynamically constructing and configuring a conversational agent learning model. Various aspects of the conversational agent learning model may be constructed and updated without continuous intervention of a domain administrator. A method pertaining to such approach may include retrieving a corpus of information. The corpus of information may include records from a set of repositories and external data, including data from social networks or applications. The method further may include configuring the conversational agent learning model based upon the retrieved corpus of information. The method further may include deploying the conversational agent learning model by facilitating interaction between the conversational agent learning model and a plurality of clients. The method further may include updating the conversational agent learning model to address any modification to the corpus of information.

Abstract: A system and related method exchange messages under the control of a messaging client. The method comprises splitting a content of a source message into a plurality of fragments defined by corresponding portions of its content associated with different recipients of the message. A plurality of transport messages are generated, each comprising one or more of the fragments associated with the recipients. The transport messages are submitted to a messaging server for causing it to provide the transport messages to corresponding further messaging clients of the recipients for their aggregation. A computer program and a computer program product for performing the method are also provided.

Abstract: A system for implementing a method that books and pays a retailer having a POS connected to a transaction server storing confidential user information including a retailer identification, a user code, and a user wireless device phone number. The method includes: receiving at the transaction server, from the user wireless device which can be a cell phone, an SMS containing a retailer identification; reading at the transaction server the phone number of the wireless device communicated by the carrier transporting the SMS; authentifying the phone number and retailer identification with the stored confidential user information; sending the user confidential information to the retailer POS. The user enters on the POS the user code. The POS reads and authentifies the user code with the user confidential information received from the transaction server. The retailer enters the payment information on the POS and sends it with user information to the transaction server.

Abstract: A method and system are disclosed for booking and paying a retailer having a POS, which can be a low cost thin client computer system, connected to a transaction server storing confidential user information including a retailer identification, a user code and a user wireless device phone number, said method comprising the steps of receiving at the transaction server, from the user wireless device which can be a common cellphone, an SMS containing a retailer identification, reading at the transaction server the phone number of the wireless device communicated by the carrier transporting the SMS, authentifying said phone number and retailer identification with the stored confidential user information and sending the user confidential information to the retailer POS, the user entering on the POS the user code and the POS reading and authentifying the user code with the user confidential information received from the transaction server, the retailer entering the payment information on the POS and sending it with
