\"NewThe Current Index to Statistics (CIS) is now hosted by the AMS<\/a>.\u00a0 It is available on the MathSciNet servers from the URL mathscinet.ams.org\/cis<\/a>.\u00a0 The database is openly available using a brand new search interface.\u00a0 <\/p>\n

Some history<\/h2>\n

The Current Index to Statistics was initiated in 1975 as a bibliographic tool for statistics and probability. It has passed through several incarnations, first as a paper volume, then as a database distributed on CD-ROM, and since 1999 as an online database with a query interface. The CIS was a product of the community of research statisticians, in particular the Institute of Mathematical Statistics<\/a> and the American Statistical Association<\/a>.\u00a0 I am grateful for the support we received from the statisticians for the move of the CIS data.\u00a0 Elyse Gustafson, the Executive Director of the IMS, deserves special thanks, as she was extraordinarily helpful in making this happen.<\/p>\n

In the data we received from the CIS, there are 549,840 articles\u00a0 and 11,143 book entries, for a total of 560,983 items.\u00a0 Items in the CIS are tagged with keywords.\u00a0 Many, but not all, have a summary or abstract attached.\u00a0 In the coming year, we will be matching the CIS items against the Mathematical Reviews database, to provide cross-linking, as well as to enhance MathSciNet<\/a> by adding the articles and books that are not in our database already.<\/p>\n

Some user tips<\/h2>\n

Search begins with a single box.\u00a0 The Search Tips<\/span> link can help you define your search from the start box using search codes, as described below.\u00a0 Alternatively, you can search, then begin refining your search using the Refine Search<\/span>\u00a0overlay.<\/p>\n

A simple search<\/h3>\n

Here is how to start a search using just the term “bootstrap”: enter the term in the search box and click Submit<\/span>.<\/p>\n

\"The<\/p>\n

A simple search like this will look for the term in any field. This search returns 5,947 matches.\u00a0 Here is a typical match:<\/p>\n

\"A<\/p>\n

The number in the top left, CIS-205226, is the ID number for the item in the CIS database.\u00a0 In the second row, we see the authors’ names and the title of the paper.\u00a0 The author names are active.\u00a0 Clicking on one will add that name to the search query.\u00a0 Here is the result on clicking on the first author’s name in the example:<\/p>\n

\"The<\/p>\n

The same is true of the title of the journal and the various keywords given with the item: clicking one of them will add it to the search query.\u00a0 You can remove<\/em> search terms added this way by clicking the minus sign in the bubble around the term.<\/p>\n

You may also have noticed that this item has its author summary displayed.\u00a0 You can toggle that with the Format<\/strong> option.\u00a0 The three formats available are 1. With summary,\u00a0 2. Brief, and 3. BibTeX.\u00a0 Selecting “Brief” makes any summaries disappear, but the rest of the format is the same.\u00a0 Selecting “BibTeX” presents all the results in BibTeX suitable for copying and pasting into your files.<\/p>\n

You can fine-tune the search results after a simple search by using the Refine Results<\/span> button.\u00a0 This produces an overlay:<\/p>\n

\"The<\/p>\n

You can choose to refine by Keywords, Authors\/Editors, or Journals.\u00a0 Here is the table of Authors\/Editors options for this search:<\/p>\n

\""Refine<\/p>\n

The options are pulled from the database.\u00a0 For instance, you automatically see the top three most frequent author names in the search results.\u00a0 The slider bar allows you to see the top ten.\u00a0 You can change the sorting by clicking the symbol after Author<\/strong> in the overlay list.\u00a0 The added search terms are not applied until you click Apply filters<\/span>.\u00a0 Thus, you could select “Hall, Peter” (Count: 186) from this table, then go back to the Keywords table and select “Jackknife” (Count: 131).\u00a0 \u00a0This would bring the number of matches to 4.<\/p>\n

A fielded search<\/h2>\n

If you have a fairly particular search in mind, you can start right off with a narrower search by using fields.\u00a0 (A list of field codes is given after the example.)\u00a0 For instance, suppose I wanted to search for “bootstrap”, but only in the title.\u00a0 I could use the search:<\/p>\n

\"Use<\/p>\n

Now there are 2,421 matches.<\/p>\n

\"Bootstrap<\/p>\n

It is still possible to use the Refine Results<\/span> option, as before.\u00a0 But you can also add search terms and fields to the search box.\u00a0 For instance, you can add a keyword search for central limit theorem<\/strong>:<\/p>\n

t:bootstrap k:central limit theorem<\/pre>\n
This will cut the results list down to 25 matches.\u00a0 Note that I did not use double quotes around the 3-word search term\u00a0central limit theorem<\/strong>.\u00a0 Once I give a search field operator, the search assumes that everything after that is part of the term (joined by Boolean ANDs<\/strong>) until it reaches another operator.<\/p>\n
Search fields:<\/h3>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Search operators<\/h3>\n
You can further fine-tune your searches by adding search operators.\u00a0 We offer two forms for each of the primary Boolean operators.\u00a0 (The variants do the same thing, but some people prefer one over the other.)<\/p>\n
Logical<\/h4>\n\n\n\n\n\n\n\n\n\n\n\n
Operator<\/th>\nDefinition<\/th>\nQuery<\/th>\nResult<\/th>\n<\/tr>\n<\/thead>\n
AND<\/td>\nBoolean AND operator (must be all uppercase otherwise matches the word “and”)<\/td>\nMarkov AND process<\/td>\nreturns all documents that contain both “Markov” and “process”<\/td>\n<\/tr>\n
&&<\/td>\nBoolean AND operator<\/td>\nMarkov && process<\/td>\nreturns all documents that contain both “Markov” and “process”<\/td>\n<\/tr>\n
OR<\/td>\nBoolean OR operator (must be all uppercase otherwise matches the word “or”)<\/td>\nMarkov OR process<\/td>\nreturns all documents that contain either “Markov” or “process”<\/td>\n<\/tr>\n
||<\/td>\nBoolean OR operator<\/td>\nMarkov || process<\/td>\nreturns all documents that contain either “Markov” or “process”<\/td>\n<\/tr>\n
NOT<\/td>\nNot operator (must be all uppercase otherwise matches the word “not”)<\/td>\nNOT process<\/td>\nreturns all documents that do not contain”process”<\/td>\n<\/tr>\n
!<\/td>\nNot operator<\/td>\n! process<\/td>\nreturns all documents that do not contain “process”<\/td>\n<\/tr>\n
|<\/td>\nindicates \u201cOR\u201d not \u201cAND\u201d for the next operator<\/td>\n|t:markov process<\/td>\nreturns all documents that contain “markov” or “process”<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Proximity<\/h4>\n
To search for phrases, use double quotes around the phrase.\u00a0 For instance, the search for “stochastic differential equations”<\/b> will return all documents that have the the exact phrase stochastic differential equations<\/strong>.\u00a0 This search would avoid matching items that contained any extra words in between.\u00a0 In particular, it would not<\/em> match the phrase stochastic partial differential equations<\/strong>\u00a0or “stochastic ordinary differential equations”.\u00a0 If you want to allow other words in the middle of the phrase, you use the tilde character followed by the maximum number of words that can appear in between the search words, <\/b><\/span>\u00a0e.g.\u00a0“stochastic differential equations”~1<\/b>.\u00a0 For comparison, the search (anywhere) for “stochastic differential equations” <\/b>matches 2,970 items; the search (anywhere) for “stochastic differential equations”~1<\/b> matches 4,289 items.
\nNote: this same proximity syntax works in MathSciNet.<\/em><\/p>\n
Wildcard<\/h4>\n
If you want to find words that start with\u00a0oper<\/b>\u00a0you can use the wildcard operator\u00a0*<\/b>, so in this example you would input\u00a0oper*<\/b>.<\/p>\n
Range query<\/h4>\n
To search for items that appear in a given range of numbers. This operator is useful for specifying a range of years (inclusive). For example to get all documents published between 2010 and 2012 try the following<\/p>\n
y:[2010 2012]<\/pre>\n
You can also use it for volume numbers, as in<\/p>\n
j:annals of probability v:[40 45]<\/pre>\n
Try it yourself!<\/h2>\n
Most of the elements of searching the CIS are intuitive.\u00a0 You should be able to get fairly far by trying the “obvious” thing.\u00a0 If you get stuck, try opening the\u00a0Search Tips<\/span>.\u00a0 As explained in this post, there are also some very useful, more advanced things you can do.\u00a0 You can discover others by checking out the online tips and, most of all, by experimenting with the CIS.<\/p>\n
