Yahoo! Search BOSS

BOSS (Build your Own Search Service) is Yahoo!’s open search web services platform. The goal of BOSS is simple: to foster innovation in the search industry. Developers, start-ups, and large Internet companies can use BOSS to build and launch web-scale search products that utilize the entire Yahoo! Search index. BOSS gives you access to Yahoo!’s investments in crawling and indexing, ranking and relevancy algorithms, and powerful infrastructure. By combining your unique assets and ideas with our search technology assets, BOSS is a platform for the next generation of search innovation, serving hundreds of millions of users across the Web.

Update: (11/19) There’s still a chance of an error (no related tweets, empty results, slow page loads). All of them seem due to Twitter’s Search API (rate limiting). If you have issues try again in 5-10 minutes. You can also check out the screenshots below. (11/15) App Engine limits were reached (and fast). Appreciate the love and my apologies for not fully anticipating that. Google was nice enough though to temporarily raise the quota for this application. Anyways, this was more to show a cool BOSS developer example using code libraries I released earlier, but there might be more here (deserving much more support). Stay tuned.

Here’s a screenshot as well (which should hopefully be stale by the time you read this).

Basically this service boosts Yahoo’s freshest news search results (which typically don’t have much relevance since they are ordered by timestamp and that’s it) based on how similar they are to the emerging topics found on Twitter for the same query (hence using Twitter to determine authority for content that don’t yet have links because they are so fresh). It also overlays related tweets via an AJAX expando button (big thanks to Greg Walloch at Yahoo! for the design) under results if they exist. A nice added feature to the overlay functionality is near-duplicate removal to ensure message threads on any given result provide as much comment diversity as possible.

Freshness (especially in the context of search) is a challenging problem. Traditional PageRank style algorithms don’t really work here as it takes time for a fresh URL to garner enough links to beat an older high ranking URL. One approach is to use cluster sizes as a feature for measuring the popularity of a story (i.e. Google News). Although quite effective IMO this may not be fast enough all the time. For the cluster size to grow requires other sources to write about the same story. Traditional media can be slow however, especially on local topics. I remember when I saw breaking Twitter messages describing the California Wildfires. When I searched Google/Yahoo/Microsoft right at that moment I barely got anything (< 5 results spanning 3 search results pages). I had a similar episode when I searched on the Mumbai attacks. Specifically, the Twitter messages were providing incredible focus on the important subtopics that had yet to become popular in the traditional media and news search worlds. What I found most interesting in both of these cases was that news articles did exist on these topics, but just weren’t valued highly enough yet or not focusing on the right stories (as the majority of tweets were). So why not just do that? Order these fresh news articles (which mostly provide authority and in-depth coverage) based on the number of related fresh tweets as well as show the tweets under each. That’s this service.

To illustrate the need, here’s a quick before and after shot. I searched for ‘nba’ using Yahoo’s news search ordered by latest results (first image). Very fresh (within a minute) but subpar quality. The first result talks about teams that are in a different league of basketball than the NBA. However, search for ‘nba’ on TweetNews (second image) and you get the Kings/Warriors triple OT game highlight which was buzzing more in Twitter at that minute.

Petri Net

What is a Petri Net?

A Petri net is a graphical and mathematical modeling tool. It consists of places, transitions, and arcs that connect them. Input arcs connect places with transitions, while output arcs start at a transition and end at a place. There are other types of arcs, e.g. inhibitor arcs. Places can contain tokens; the current state of the modeled system (the marking) is given by the number (and type if the tokens are distinguishable) of tokens in each place. Transitions are active components. They model activities which can occur (the transition fires), thus changing the state of the system (the marking of the Petri net). Transitions are only allowed to fire if they are enabled, which means that all the preconditions for the activity must be fulfilled (there are enough tokens available in the input places). When the transition fires, it removes tokens from its input places and adds some at all of its output places. The number of tokens removed / added depends on the cardinality of each arc. The interactive firing of transitions in subsequent markings is called token game

1.我无法理解他究竟这样会为他带来什么好处? 不过他就习惯性的张狂，我觉得这种初入实验室还低调见人就问好，到现在这样，借着跟博士关系好就开始张狂的人十分的令人痛恨，之前出现半个，但是现在又出现了一个，或者一个半这样的人，真是叫人不爽，总是自我安慰这样的鸟人又不能影响到我什么，但是我看着这样的鸟人在我面前晃，我还是觉得不爽

2.无法理解能把那么一点钱拖了大半月还要分开2半给的人是怎么样一个人，昨天我怒了，连韩国经典国骂都出来了，骂中国国骂已经不能表现出我的出离愤怒了。不过想想当着人面满脸堆笑，换背地又骂人，还真够小人的我lol

3.继续得低调下去，虽然这2天心情极度不爽，hmm 昨天差点还跟实验室心底最善良，最该找到女人的明瑾同学吵上一把，还好俺们明瑾心底善良不跟我一般见识，唉，只是可惜了我那开了120天的机器

4.待续……

真是随着年龄见长，其他啥都没长就是脾气长了。。。

只能感慨，一样米，养百样人

只是简单的做一些应用，之前是用windrop的，这回想试一试新的，看最近大家喊的比较多的3proxy就装来试一试，其实安装过程很简单，下载源码，就make Makefile.linux 然后再 make Makefile.linux install 即可

其余的就是一个cfg的配置问题 

system "echo Hello world!"
# you may use system to execute some external command if proxy starts

做了个匿名的HTTP代理和认证的socks代理，搞完以后发现……不能在后台默认运行……

后来仔细找.sh发现在scripts文件夹下有自动安装……很吐血 lol  不过cfg文件还得自己配置  lol
