![]() Our cross-project study successfully discovers overlapping rPairs among projects of similar functionality and finds that cross-project rPairs are more likely to be correct than project-specific rPairs. In addition, the proposed ranking algorithm improves the rPair extraction accuracy by bringing correct rPairs to the top of the list. Our further evaluation against the state of art shows that our technique can achieve a higher precision and recall. We achieve a reasonable accuracy in nine large and popular code bases written in C and Java. In addition, we propose a ranking algorithm on the rPair results and study cross-project rPairs on two sets of software with similar functionality, i.e., media browsers and operating systems. This paper proposes a simple and general technique to automatically infer semantically related words (referred to as rPairs) in software by leveraging the context of words in comments and code. On the other hand, many words that are semantically related in English are not semantically related in software. However, it is limited to rely on resources such as English dictionaries and WordNet to obtain semantically related words in software because many words that are semantically related in software are not semantically related in English. Therefore, it is crucial for keyword-based code search to expand queries with semantically related words, e.g., synonyms and abbreviations, to increase the search effectiveness. The difficulty of code search lies in the inability to guess the exact words used in the code. Not sure why or if it's a good idea, but I do it anyway.Code search is an integral part of software development and program comprehension. I'll bid something arbitrary like £213.46 for something that I've valued at a little over £200. Maybe someone else will outbid you in those last seconds, just walk away, or, if you're lucky, you might win.Īnd as a final weird habit of mine, I never bid a round number. Sometimes the auction might already be higher than that, so just walk away. The only way to play eBay is to bid your fair valuation at the very last moment. ![]() Add another couple of people using this 'strategy' and the price will escalate. Someone else who wants one but doesn't really know the value of the item might bid up in £10 increments until he beats you at £210. You've decided the item is worth, say £200 and you've bid that much with 5 days left to go. You've tipped your hand and some folks will use that as a judgement of value for the item. If you've decided what the item is worth to you and you bid early on, you'll likely get lowballers progressively bidding a bit higher. Yes, this is a fundamental problem with eBay. And it is very important for the community to know that these machines still exist - the polar opposite is the crushing blow when yet another classic is destroyed in the action of some worthless hollywood movie. On the other hand, the insane prices achieved at auction has brought out some of the really rare cars that otherwise would never be offered for sale and the increased sale price has also increased the usual restoration budget saving a lot of rare and historically important vehicles from the crusher. I was always interested in muscle cars (an intangible prize is offered to anyone who knows what my avatar is a photo of ) and in recent years have noticed in that community people claim "I just simply can't afford not to sell this car" and then the vehicle leaves the owner and is purchased by a "collector", someone who will never drive, has no emotional connection and knows very little about their cars except that someone else told him it's "cool". Also, the computer may re-appear next week with "relisted due to non paying scumbag" appended to the description.īut I will comment on auction houses that sell classic cars as that's something I have mixed feelings about. Not going to comment on price because I don't really care (and the house rules). It looks like a very good (and somewhat maxed out) computer and the seller was fairly honest in the description (but could have included more/better photos). This is a good example of a bidding war, 3 people were obviously interested in the computer offered. I looked the auction up as I was interested to find out if it was a Commodore or Amiga Tech. If you bid your maximum early on in the auction you will probably find that other people will reassess what their max bid will be.Īnyway, back to the topic at hand. when I come back after the auction has ended I discover if I have bought the item or not. I simply input the auction number and my max bid then get on with my life.
