Review criteria
1、Number and quality of example sentences. I believe example sentences are the most important feature of a dictionary. Looking at example sentences is the fastest way to figure out the answers to three critical questions: 1 What does this word mean? 2 In what situations do native speakers use this word? 3 What words and grammatical patterns typically appear with this word? Examples also give you ready-made phrases that you can “steal” and use in your own sentences.
2、Number and quality of definitions. In a learner’s dictionary, definitions should tell the learner about the most common situations and contexts in which a word is used. If 90% of the sentences with the verb wag are about tails, the definition should mention tails, even if sometimes the word is used in other ways. Such a definition is easier to understand and more useful than a more general, abstract one.
3、Accuracy and completeness of phonetic transcriptions. Dictionaries should list all the common pronunciations of a word in both British English (RP) and American English (General American).
4、Coverage of American English. A learner’s dictionary should give accurate and complete information on American pronunciations, American words, and differences between British and American usage.
5、Quality and coverage of recordings. Audio recordings should sound clear (no technical defects). It should be indicated which transcription is pronounced and the recording should match this transcription. Ideally, there should be a recording for each British and American transcription, as well as for word forms (-s, -ed, etc.)
6、Additional content, such as pronunciation exercises, synonyms, usage information, pictures, etc.
7、User friendliness. The software should enable the user to perform all the common tasks (looking up a word, playing a recording, etc.) easily and without unnecessary clicking. It should offer all the expected features (like copy & paste) and should support all the expected input operations (standard keys, drag-and-drop, scrolling with the mouse wheel).
8、Responsiveness. The software should do its job without annoying delays.
9、Search engine. (Technically, searching is part of “User friendliness”, but it is so important in a dictionary that it deserves its own category.) If a word has many spellings (e.g. hard-pressed/hard pressed), it shouldn’t matter which one you search for. It shouldn’t matter if you type “between a rock and a hard place”, “caught between a rock and a hard place”, “hard place” or “rock” – the phrase you’re looking for should always be returned in the search results.
Layout. Definitions, phonetic transcriptions and example sentences should be laid out in a clean and readable way. The user should not feel overwhelmed by interface elements.
10、Price.
总结：
Summary
As you see, there is no clear winner – no dictionary that would be best (or even close to best) in all the categories. That said, here are a few thoughts:
1、If you are learning American pronunciation, you should probably verify the pronunciations of words in an American dictionary like the online Merriam-Webster Dictionary. The information on AmE in British dictionaries cannot be fully trusted (the LDOCE is the most trustworthy).
2、If you are focused on AmE and you want to use just one dictionary, the only good choice is the Longman Dictionary of Contemporary English.
3、It is difficult to recommend the best dictionary for everyone. The Longman has the richest, most helpful content, but its software interface is an obstacle. On the other hand, the Cambridge and the Collins (5th edition) are the most pleasant to use. You could choose the Longman’s great content and put up with its annoyances, or you could decide that efficiency and convenience are more important. The decision will depend on your specific needs and your tolerance for bad software.
4、Added Oct 2010: After a year, I have decided the LDOCE is too painful to use.这里是说LDOCE的软件当时做得超烂，所以使用起来超痛苦。
Cambridge剑桥3 内容得分：B-/C+ 软件综合体验：B
Collins科林斯5 内容得分：B/C+ 软件综合体验：B
Longman朗文5 内容得分：A-/A- 软件综合体验：C
Oxford牛津7 内容得分：B/B- 软件综合体验：C
Collins科林斯6 内容得分：D-/F+ 软件综合体验：F
Cambridge剑桥3 ： 很好的英国英语学习词典，对于美国英语有点平庸。软件体验不错。
Collins科林斯5 ： 很好的英国英语学习词典，对于美国英语有点平庸。软件体验不错。
Longman朗文5 ： 非常好的美国英语学习词典，可惜软件体验糟透了。
Oxford牛津7 ： 很好的英国英语学习词典，足够用来学习美国英语。糟糕的软件体验。
Collins科林斯6 ： 如果将词典比作汽车的话，Collins科林斯6简直就是独轮车/手推车。
LDOCE的确不错，不过该评论者最后得出的结论有点儿矛盾，
不知道为什么说：After a year, I have decided the LDOCE is too painful to use. 本帖最后由 xiaokeai 于 2016-4-24 16:08 编辑

因为他比对的是PC软件版的词典，LDOCE应该属于做得超烂的那种。跟文本沒有关系。 朗文确实推崇的人最多 这些词典放在一起搭配使用是最好的 作者如果用过mdict，一定会觉得会方便吧。他博客里推荐了一个ldoce5外壳软件。 作者没有用过韦氏，眼界有限 本帖最后由 lxchen2001 于 2016-4-26 04:27 编辑
09年至今，网络发生的巨大变化。
在线的vocabulary.com 基于wordnet，单词的解释说明简单易懂，例句丰富。侧重美语用法。
vocabulary.com + 朗文5 + 牛津ODE + 读者文摘的Use the right word 是我的首选。感谢这里的众多热心人提供了这么难得的资源。 lxchen2001 发表于 2016-4-26 04:26
