Abstract: A securities processor includes non-volatile storage, a first-in-first-out queue maintained in the non-volatile storage to store events, a random access memory, and an order book maintained in the random access memory to store one or more events corresponding to quotes or outstanding orders related to a security. A matching process receives the events from the queue, determines whether the event can be matched with a contra-side event stored in the order book, and executes a transaction between the received event and a matched contra side event if a match is found.

Abstract: A sentiment analysis computing system includes a storage medium and a processing system. Sentiment input is received from audience members viewing a streamed/webcasted event. The received input is stored to the storage medium. A time slice of the webcasted event is determined and sentiment inputs that are within that time slice are obtained. A sentiment value is calculated for the determined time slice based on aggregated sentiment values. The calculated sentiment value for the time slice is then output by the sentiment analysis computing system.

Abstract: Systems and techniques for capturing audio and delivering the audio in digital streaming media formats are disclosed. Several aspects of the systems and techniques operate in a cloud computing environment where computational power is allocated, utilized, and paid for entirely on demand. The systems and techniques enable a call to be made directly from a virtual machine out to a Public Switch Telephone Network (PSTN) via a common Session Interface Protocol (SIP) to PSTN Breakout service, and the audio to be delivered onward to one or more Content Delivery Network (CDN). An audio call capture interface is also provided to initiate and manage the digital streaming media formats.

Abstract: A system for performing due diligence on electronically stored documents is provided. A dynamic due diligence item (DDDI) is created by one user and associated with a particular document or piece of information by the system. The created DDDI is assigned to another user. The created DDDI is then routed by the system over a computer network to another user for review of the DDDI and the associated particular document or piece of information. In certain instances, after receiving the notification and opening the document, the system may enforce upon the second user a required action when the DDDI is presented.
