A chatbot maintains a conversation with a user by providing a plurality of separate conversational tiers that allow the chatbot to interact with the user, each of the conversational tiers having a set of production rules that are independent of production rules for other ones of the tiers. The production rules indicate a flow of conversation between the user and the chatbot. The chatbot selects one of the conversational tiers based on previous conversational tiers used by the chatbot in connection with conversing with the user and based on content of conversations between the user and the chatbot. The chatbot responds to statements of the user according to a specific production rule that is chosen by the chatbot based on a particular one of the conversational tiers that has been selected and based on other factors. A scripting engine may match statements of the user with specific production rules.

An article having a hydrophilic surface of a material, including a base material having a surface; and a siloxane oligomer represented by Chemical Formula 1 chemically affixed to the surface of the base material wherein the organosiloxane coating comprises a reaction product of a siloxane oligomer represented by Chemical Formula 1 or a polysiloxane derived therefrom, with a phosphonic acid compound represented by Chemical Formula 2: 

Methods of material hydrophilization by siloxanes containing nitrilopoly (methylenephosphonic acid) or derivatives thereof

A method of imparting hydrophilicity to a surface of a material, which includes providing a base material having a surface; applying and chemically fixing a siloxane oligomer represented by Chemical Formula 1 to the surface of the base material to form a siloxane-modified surface; and applying a glycidol compound represented by Chemical Formula 2 to the siloxane-modified surface; and carrying out a reaction therebetween to form an organosiloxane coating having a N,N-bis(hydroxyalkyl)aminoalkyl group: wherein R, R, and Rare the same or different and are each independently hydrogen or a C1 to C3 alkyl group, A is a single bond or a C1 to C5 alkylene group, and n ranges from 2 to 30; 

Methods of material hydrophilization by glycidol-containing siloxanes
