eBay Search Science: Leveraging Behavioral Data Analysis for Effective Query Reformulation
Brian will talk about combing through behavioral log files with Scala on Hadoop in order to generate large data sets used to drive dynamic, online query rewrites at eBay. He’ll cover the product/feature pipeline from ideation to data mining, prototyping, statistical analysis, offline side by side analysis, human judgment, online experimentation, and finally launch.

Analyzing online traffic and making sense of all the data is something digital marketers do every day. After all we need to understand what’s going on in order to grow the business. Sometimes our assumptions are based on past experiences, sometimes we can support them with data, but quite often they are based on pure logic. Are they really? Over the years we’ve worked with numerous clients and learned that some assumptions are proven wrong more often than not.
We are looking for people who are interested in working from home.

2011 Search Query Rewrites - Synonyms & AcronymsBrian Johnson
July 27, 2011 Bay Area Search Presentation
Brian Johnson, Engineering Director, Query Services @ eBay
Query expansion is an important part of of the search recall for all search engines. In this talk I'll discuss some of the general trend driving Hadoop adoption within the Search Query Services team at eBay, and the types of algorithms/techniques we've moved to Hadoop at eBay. Over time we've moved from smaller, editorial data sets to large machine generated data sets mined from behavior log data, items/listings, catalogs, etc. One common workflow is to mine large candidate rewrites/expansions data sets from multiple data sources, use crowd sourced human judgment to classify a subset of the candidates (true positive, false positive), use machine learning techniques discard false positives, run automated validation on the final data set, and automatically push to production.
Ravi Jammalakadaka, Senior Applied Researcher, Query Services @ eBay
Ravi is a real engineer. Not a pointy haired manager like the previous speaker. Expect some real engineering:-) He'll be doing a literature review for acronym mining and discussing a real world implementation.
Title: Mining Acronyms From Raw Text
Abstract: Significant number of eBay products are known by their acronyms. eBay query expansion service expands user queries by their acronym equivalents to increase recall. The challenge is to mine acronyms from either seller ( ex. item descriptions, titles) or buyer ( ex. queries) data.
Ravi will present the state of the art algorithms from recent conferences that mine acronyms from raw text and present their limitations. He will present a new acronym mining algorithm that seeks to address the limitations identified with previous algorithms. He will present a machine learning classifier that seeks to remove the false positives generated from the acronym mining algorithm.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

A Study of Variable-Role-based Feature Enrichment in Neural Models of CodeAftab Hussain
Understanding variable roles in code has been found to be helpful by students
in learning programming -- could variable roles help deep neural models in
performing coding tasks? We do an exploratory study.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Search Science Recall & Spam
April 23, 2015
BRIAN JOHNSON
With more than 100 million active users globally, eBay is
the world's largest online marketplace, where practically
anyone can buy and sell practically anything. Founded in
1995, eBay connects a diverse and passionate community
of individual buyers and sellers, as well as small
businesses. Their collective impact on ecommerce is
staggering: In 2014, the total value of goods sold on eBay
was $82 billion -- more than $2,500 every second.

We see two sets A and B . There are three elements in their intersection and a total of eight elements that
appear in A or B or both. Thus, JaccardSimilarity(A, B) = 2/5.

• Rationale: The goal of this metric is determine if the co-occurrence of
the candidates in the description is significantly more than the
random chance of them co-occurring.
29. Features: Neighborhood Similarity
• Rationale: Two synonym candidates A and B, will tend to
have similar neighbors (viz keywords) surrounding them.

(It was very hard to find a good example of this that brought in obviously wrong data above the fold: these issues are generally more subtle, showing up in deterministic sorts and in slower processing time. If you come up with another good example to include, that would be great.)
There are many entity names, including many brands, which are identical to (Cowboys) or share components with (e.g. Red Bull) common terms that describe our inventory. By identifying entities and by using whole query context, we can provide expansions only when appropriate (e.g. no Redder Bull or Crimson Bull). We can also decide the confidence of an expansion compared to the original (e.g. as is usually done in spell check).
For the cowboy(s) hats, Cowboys seems to mainly refer to the football team; there are a few cowboy hats where someone used “cowboys” instead of the possessive, but not many. For the toys, the plural form is definitely more common but the singular is also used in titles even in sets (bottom row of pictures has the singular; top row the plural); so, we want to use both forms to get the maximum inventory for this.
