"Does Anyone Know How to Get Good Answers?" How Social Network Questions Shape Replies
2013Co-Authors: Jaime Teevan, Meredith Ringel Morris, Katrina PanovichAbstract:Social networking tools make it easy for people to ask questions of large groups of their personal acquaintances. In this article, we explore how the questions people ask of their social networks via Status Message updates shape the replies they receive. We present the results of a survey of 624 people, in which participants were asked to share the questions they have asked and answered of their online social networks. We observe interesting variations in how people ask natural, real-world questions that suggest that the effectiveness of a question posed to one’s social network could depend on who asks the question, when the question is asked, and how the question is phrased. To understand whether these factors actually do shape question replies, we conducted a controlled study in which 282 participants posted variants of the same question as their Status Message on Facebook. By analyzing the quantity, quality, and speed of the responses, we find that by controlling the time of day a question is posed and how the question is phrased, and by maintaining a strong network, a person can increase the likelihood of quickly receiving many high-quality answers.

factors affecting response quantity quality and speed for questions asked via social network Status Messages
International Conference on Weblogs and Social Media, 2011Co-Authors: Jaime Teevan, Meredith Ringel Morris, Katrina PanovichAbstract:Social networking tools enable people to easily ask questions of large groups of personal acquaintances, but the effectiveness of doing so depends in part on how the question is phrased. In this paper we present a study in which 282 participants posted variants of the same question as their Status Message on Facebook. We analyze the quantity, quality, and speed of the responses each variant received. We find that by ending an information need with a question mark, explicitly scoping the audience, and being succinct, a person can increase the likelihood of quickly receiving many high-quality answers.

what do people ask their social networks and why a survey study of Status Message q a behavior
Human Factors in Computing Systems, 2010Co-Authors: Meredith Ringel Morris, Jaime Teevan, Katrina PanovichAbstract:People often turn to their friends, families, and colleagues when they have questions. The recent, rapid rise of online social networking tools has made doing this on a large scale easy and efficient. In this paper we explore the phenomenon of using social network Status Messages to ask questions. We conducted a survey of 624 people, asking them to share the questions they have asked and answered of their online social networks. We present detailed data on the frequency of this type of question asking, the types of questions asked, and respondents' motivations for asking their social networks rather than using more traditional search tools like Web search engines. We report on the perceived speed and quality of the answers received, as well as what motivates people to respond to questions seen in their friends' Status Messages. We then discuss the implications of our findings for the design of next-generation search tools.

CSCW - To search or to ask: the routing of information needs between traditional search engines and social networks
Proceedings of the 17th ACM conference on Computer supported cooperative work & social computing, 2014Co-Authors: Anne Oeldorf-hirsch, Jaime Teevan, Meredith Ringel Morris, Brent Hecht, Darren GergleAbstract:In Status Message question asking (SMQA), members of social networking sites make use of Status Messages to express information needs to friends and contacts. We present findings from a laboratory study that examined 82 participants' SMQA behaviors in the broader context of online information seeking. When given the option of using a search engine and/or a social network, participants leveraged SMQA for 20% of their information needs, most often posing a question to their network in addition to issuing a query. We show the important roles played by the specificity of the information need and the perceived audience of a given network on routing decisions. We then demonstrate that routing decisions have varied effects on participants' satisfaction, information value, and trust of outcomes. In addition to highlighting the complementary advantages and disadvantages of search and SMQA, our findings suggest that search engines can better address a meaningful portion of people's information needs by integrating SMQA capabilities into their systems.

MPLS Label Switched Path (LSP) Pseudowire (PW) Status Refresh Reduction for Static PWs
2017Co-Authors: George Swallow, Elisa Bellagamba, Luca MartiniAbstract:This document describes a method for generating an aggregated pseudowire (PW) Status Message transmitted for a statically configured PW on a Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) to indicate the Status of one or more PWs carried on the LSP. The method for transmitting the PW Status information is not new; however, this protocol extension allows a Service Provider (SP) to reliably monitor the individual PW Status while not overwhelming the network with multiple periodic Status Messages. This is achieved by sending a single cumulative summary Status verification Message for all the PWs grouped in the same LSP.

Pseudowire Status for Static Pseudowires
2012Co-Authors: George Swallow, Giles Heron, Matthew Bocci, Luca MartiniAbstract:This document specifies a mechanism to signal Pseudowire (PW) Status Messages using a PW associated channel (ACh). Such a mechanism is suitable for use where no PW dynamic control plane exits, known as static PWs, or where a Terminating Provider Edge (T-PE) needs to send a PW Status Message directly to a far-end T-PE. The mechanism allows PW Operations, Administration, and Maintenance (OAM) Message mapping and PW redundancy to operate on static PWs. This document also updates RFC 5885 in the case when Bi-directional Forwarding Detection (BFD) is used to convey PW Status-signaling information. [STANDARDS-TRACK]

GLOBECOM - Vehicular and Messaging Throughput Tradeoffs in Autonomous Highway Systems
2015 IEEE Global Communications Conference (GLOBECOM), 2015Co-Authors: Yuyu Lin, I RubinAbstract:Emerging autonomous vehicular technology advances facilitate the development of intelligent traffic regulation systems, aiming to configure vehicular mobility patterns to enhance in-road safety and accommodate high rate transport of vehicle-to- vehicle messaging flows. To date, mechanisms that are implemented to regulate vehicular mobility and those employed to provide for the communications of Message flows across the highway, have been studied independently. In this paper, we investigate mechanisms that are used to regulate the mobility of highway vehicles, as they form distinct platoons, while also aiming to disseminate high priority safety and lower priority Status messaging flows. We identify desired configurations of platoon entities, and the underlying setting of the parameters of the spatial TDMA scheduling scheme, aiming to satisfy the Message delay limits required for the distribution of safety Messages while providing for high throughput rates for the transport of Status Message flows. Under each vehicular traffic congestion regime, we demonstrate the design options that are available in determining the system's performance behavior, trading data messaging vs. vehicular traffic throughput rates.
