Abstract: Techniques are provided for ranking time-series including previously detected anomalous fact quantity changes over an associated time interval. Time-series are received, and for each time-series, a normalized fact quantity change is determined, and each time-series is ranked based in part on the normalized fact quantity change. A normalized fact quantity change may be determined by determining a normalization factor over the time interval, and then determining a product of the normalization factor and the absolute value of the fact quantity change of that time interval. Alternatively, a normalized fact quantity change may be the product of the normalization factor, a predetermined order factor, and the absolute value of the fact quantity change. The normalization factor is determined by analyzing the distribution of the fact quantity change over dimension values of the dimension(s) associated with the time-series to determine the number of values in which the fact quantity is concentrated.

Abstract: A system and method of generating a preview of a file attachment includes receiving the file attachment in an email server. The file attachment can be received either during composition of the email or when receiving an inbound email. Determining if the file attachment is a previewable file type or compressed file type or non-previewable file type and automatically generating a preview of the file attachment including identifying the file attachment, parsing the file attachment to identify content of the file attachment, wherein the identified content includes a pagination of the file attachment. A file structure for each page of the file attachment is created and then saved to an attachment store in the email server.

Abstract: Described herein is a system and method for classifying detected anomalies. Detected anomaly data comprising a plurality of anomaly data points is received. The detected anomaly data is labeled with a plurality of attributes using label logic for each of the plurality of attributes. The detected anomaly data is classified into one of a plurality of classifications based upon the attributes using a rule-based classification algorithm. The rule-based algorithm further determines a result for at least some of the anomaly data points. The classified detected anomaly data and the corresponding determined results are provided, for example, to a user.

Abstract: A content item hosted by a content item source (such as a weblog post of a weblog) may receive updates (e.g., comments submitted by users), and may be discussed among users in a chat group of a chat service. The content item source and the chat service may coordinate to notify users of updates to the content item, and to share content regarding the content item. When a user requests to subscribe to updates of the content item, the content item source may invite the user to join a chat group of the chat service created for discussion of the content item. Additionally, updates to the content item received by the content item source may be automatically posted as messages in the chat group, and messages posted in the chat group regarding the content item may be automatically posted as updates to the content item at the content item source.
